“They’re just so impressive - the lack of weight.” “Holding power for weight is phenomenal. Nothing on the market comes close.”

“It’s sweet! I love the grip without excessive rope wear, plus heaps of mounting options; and it’s mega light - every gram counts!”

“We’ve been making custom lightweight blocks for years. Now there’s no need. These blocks are super light with great holding power. We go with manual mode on the main and auto on the kite” Photo - Andrea F ancolini, www.af ancolini.com

BALL BEARING &

RATCHET

Ball Bearing Orbit Blocks™ boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and a Dyneema® rope link head. Their precision design allows the optimum number of ball bearings in loaded areas and eliminates them in inactive areas. Ineffective mass is reduced even further through fibre-reinforced composites in the block head, cleat arms and beckets.

Less fatigue, more control The world’s best ratchet block is now even better. It has all the holding power of its predecessor, but with superior i rope wear performance. f It’s lighter, It’s lig and it’s the only ratchet block with both manual and full automatic modes*2. Control swittches on both sides of the block remain accessible whether fitted on port or starboard side, and thee NC C-machined alloy sheave and simple mechanism ensures superb reliability and durability.

Lightweight Kilogram for kilogram of working loaad, BB and RT Orbit Blocks™ are the world’s lightest*1. To gain peak performance, we engineered out the heavy steel load straps, head post, full-length fasteners, and cleating accessories. Through extensive research and developmeent, we replaced all possible metal components with high-tech polymers and fibre equivalents. The unique BB block orbiital design allows the bearing to only be in the active areas of the floating sheave. This minimises the mass of tthe inactive return race and hub. Weight and bulk are fur ther reduced in the different block configurations. Some models feature a through-sheave beckett arraangement. The result? The lowest weight possible! Multi-sheave blocks hhave oonly single intermediate cheeks and an ultra-light and efficient head arrangement. This givves a 30% weight saving advantage over the nearest competitor. Other brands just link together their sinngle blocks. This results in unnecessary double cheeks between each sheave, held together by a heavyy steeel channel across the top of the block.

Highest worrkinng load in its class The orbital ball--beariing arrangement gives the largest possible bearing race diameter. This maximises load perrformance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum fricction across the full working load range. The Dyneem ma® Link is produced from FSE Robline SK75 fibre, which is 10 times stronger and lighter thann steel, and provides the final connection from the block to the load point.

Simple aand secure attachment The Dyyneem ma® Link is easily fitted and is retained securely by a moulded retainer clip. The flexible link can be left with one end attached to the block when fitting - no more lost shacckle ppins. Thee flexiible Dyneema® Link provides lowest possible weight and profile with controlled rottationn and 0° or 90° orientation. Stainless steel swivel shackle head models are also avvailabble for continuous rotation and ultimate durability.

H h performance cleating High Both R Ronstan BB and RT Orbit Blocks™ feature strong, lightweight fibre-reinforced clleat aarms. They have a wide range of adjustment and calibration marks, perfect for seelecting your preferred cleating angle settings. The race-proven carbon-fibre reinforced Roonstaan C-Cleat™ give secure rope holding with low entry and exit efforts, and are fitteed with fairleads for fast action from any angle.

Aw wesoome ratchet block holding power Quite simpply, Ronstan Ratchet Orbit Blocks™ have the highest holding power available. The sopphisticated NC-machined sheave features Generation 2 of our patented sheave cross-hoole geeometry. Its holding power is up to 25:1*3, almost double that of our nearest competitor.r. The unique shheavee design has up to 12*3 gripping faces which directly resist loaded line movement. Traditional designns haave only 8 faces or less with an angled resistance to line movement. Our Generation 2 design has sstraight resistance faces which both distribute the load and minimise rope wear.

Automatic and maanuaal ratchet in one block Now you can enjoy the flexibility of setting up your ratchhet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement g g modes*2. In auto mode, the ratchet mechanism engages when load is applied, but switches off when it’s released. This lets the sheet run out smoothly and freely- great for rapid easing of the sheet and for gybing asymmetric spinnakers. In manual mode, the ratchet mechanism can be switched on or off as required - popular main for sheeting. *1 Dyneema® Link models. *2 Selected Series 55 models. *3 Series 70 models.

USER INSTRUCTIONS CONTENTS 1.0 Fitting of Orbit Blocks™ with Dyneema® Links 1.1 Attached at 90° (transverse) 1.2 Attachment at 0° (in-line) 1.3 Attachment to a pin, shackle, saddle, line, etc 1.4 Other attachments.

2.0 Fitting of Sheets/Lines to Beckets

• For best results, the Dyneema® Link must be attached to a mounting point with a smooth, well rounded profile.

1.2.7 (Diagram 1.2.7) Rotate the block clockwise back to 0° and pull slightly to align and tension the link symmetrically.

• Avoid attaching directly to fittings with sharp edges or rough surfaces that may damage the Dyneema® Link through abrasion or point loading. For this situation use a shackle with a smooth surface between the Link and the fitting.

1.3

Attachment at 90° (transverse) (Diagram 1.1)

1.1.1 Use a shackle key or small screwdriver to release one side of the Retainer Clip. Use a finger to hold the other side of the Retainer Clip in place. ®

1.1.2 Remove the free end of the Dyneema Link from its recess in the head of the block. 1.1.3 Pass the Link through the mounting point. 1.1.4 Press the end of the Link over the Retainer Clip and firmly back into its recess in the block. A little tension on the Link may help to settle it into position. 1.1.5 Snap the Retainer Clip back into place over the Link. An audible “click” confirms secure attachment. 1.2

Attachment at 0° (in-line) (Diagram 1.2)

1.2.1 Use a shackle key or small screwdriver to release one side of the Retainer Clip. 1.2.2 Remove the end of the Dyneema® Link from its recess in the head of the block. 1.2.3 (Diagram 1.2.3) Twist the Link anti-clockwise 360° (i.e. first twist 180° to form a figure-8 shape, then twist again). 1.2.4 Pass the Link through the mounting point, taking care to keep it twisted as described above. 1.2.5 Press the end of the twisted Link over the Retainer Clip and firmly back into its recess in the block. A little tension on the Link may help to settle it into position.

IMPORTANT: Ronstan Orbit Blocks™ have several unique becket arrangements. To avoid improper loading or failure of the becket, use only the correct method of line attachment for each type as described below. BB Single Blocks with Becket • Pass the sheet end through the becket eye and secure with a bowline or eye splice. 2.2

1.3.5 Snap the Retainer Clip back into place over the Link. An audible “click” confirms secure attachment. 1.3.6 (Diagram 1.3.6) Pass a shackle, saddle, pin, or rope end through the Link (which now has a single crossover) at 0° or 90° to the block, depending on the desired alignment. 1.4

Other Attachment

1.3.6

1.4.2 (Diagram 1.4.2) Custom lashings, strops or Links can be made from Dyneema® rope of the same diameter as the supplied link. Note; where required to fit around an object wider than the head of the block (eg a boom) the ends of the custom Link must cross each other prior to being fitted into the recesses in the head of the block. The Maximum Working Load and Breaking Load of the assembly (Block + Link) is limited by the strength of the rope and the joining method. Knots, splices, stitching, etc. will generally have a lower Breaking Load than the rope itself.

7.0 Upright Lead block alignment (Diagram 7.0)

• Ronstan BB and RT Orbit Blocks™ feature a unique Dyneema® Link head. Building on the latest trends in grand prix dinghy and ocean racing, it replaces the steel head post and shackle arrangement of traditional blocks. Ronstan Dyneema® Links are made from highest quality FSE Robline Ocean 3000 12 plait Dyneema® SK75 line, treated with S.Y.I.S. impregnation for high resistance to abrasion and UV protection. Dyneema® is a super strong polyethylene fibre that offers maximum strength combined with minimum weight. Dyneema® fibre’s high tenacity allows it to match the strength of steel at one tenth of the weight. It is more durable than polyester and has a specific strength that is 40 percent greater than aramid fibre. • To receive the maximum performance benefit from the Dyneema® Link, it must be used correctly, inspected regularly and replaced when required. • The Dyneema® Link must be attached to a mounting point with a smooth, well rounded profile without sharp edges or burrs. If in doubt, use a shackle with a smooth surface between the Link and the mounting point.

Auto Mode

5.2.1 With the block in Manual mode, turn the ratchet off by rotating the red ON/OFF knob to the OFF position.

5.0

5.2.2 Slide the black MODE switch firmly toward the red ON/OFF knob until it locks into the recess in the knob. Repeat with the MODE switch on the other side of the block.

OFF

5.2.3 The block is now in Auto mode. 5.2.4 To return to Manual mode, slide the black MODE switches on both sides of the block firmly away from the red ON/OFF knob. Now use the red ON/ OFF knob to turn the ratchet ON and OFF.

ON

axis of the block bisects the angle between line entry and exit, which must be approximately in the same plane. Misalignment or improper installation will reduce the load capacity of the block. 90 degree change in line direction, with line entry at 90 degrees to the base and line exit parallel to the base. Any variation on these line angles will reduce the load capacity of the block. • The Dyneema® Link will eventually suffer degradation from fatigue, wear and UV exposure. Like all running and standing rigging, the Link should be inspected regularly and replaced it if it shows significant amount of wear or fibre damage, or as a part of your regular boat maintenance program.

Orbit Blocks™ • Grit and sand will damage bearing systems. Ronstan Orbit Blocks™ have a precisely engineered bearing system that should be kept clean and free of sand and grit to ensure optimum performance and service life. Blocks, in particular the bearing areas, should be flushed with fresh water regularly and periodically cleaned with a mild detergent and water. • Dry lubricants such as Ronstan Sailfast silicon spray may be used to lubricate the bearing system and ratchet controls. Oil/petrochemical based lubricants must not be used. • Ronstan Orbit Blocks™ are designed and manufactured for applications on sailboats. See the Info section of the Ronstan web site and our catalogue for important customer considerations and warranty information.

Orbit Blocks™ are a no-compromise product range developed to meet the demands and expectations of the very dedicated and increasingly professional racing sailor, with characteristics including: • The highestt strength-to-weight strength-to-wei ratio. r • Minim mal friction loss, eespeccially when working at high loads. • Totaally reliable and trouble free performance. • Siimplicity of desiggn and construction to facilitate maintenance and servicing. • Elegant, functionaal styyling and finish.

Beaaring System The Orbit sheave has captivve Aceetal or Torlon® ball bearings for side thrust loads, eliminating the need for side retainer pplates. This reduces weight and allows for a wider bearing sur face that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.

Design Simpplicitty There are only 3 pprimaryy components to the block: the twin side pieces, sculptured from solid high grade aalloy, aand the one-piece sheave with its captive ball bearings. Bearings are easily rinsed cleear of salt and debris.

Fooot Blocks Thee bottom hub section is maachined from solid alloy for maximum integrity of the load bearing sttructure. The top coveer platee protects the sheave against impact, prevents dirt and grit from entering the hub area, and ccan be removed for service without removing the mounting bolts that secure the block thrrough the base plate to the deck.

Halyard Bloocks These blocks hhave bbeen designed primarily for attachment around the mast collar to lead halyarrds aftt from the mast base to the winches. The head of the block has a removablee pin w which enables easy attachment to the deck padeyes or the mast collar. Thiss method of attachment provides a low lead aft to organisers or winches.

Standd-Upp Blocks A num mber oof stand-up solutions are available for Orbit Blocks™. These incluude assemblies incorporating padeye and rubber boot with 60° or 90° orieentatioon at rest, or blocks with special swivels used with non-tumble paadeyess.

Univversal Head Headd posts of swivel blocks can be locked at 0° or 90°. The high resisstance shackles are forged in grade 17-4PH stainless steel.

Runner Blocks These blocks have a unique shape and Acetal guide rollers that help kkeep the line engaged with the sheave in running backstay appliccations.

W bing & Strop Blocks Web Thhe absence of a swivel head or shackle allows weight savings where a webbbing or rope lashing attachment is suitable. When passed through the hub of the sheave this also provides a failsafe feature. See our website for instr uctions on propper weebbing attachment.

Exceptionally ti ll high hi h strength-to-weight t th t i ht ratio. ti Captive ball bearings for side thrust loads require no side retainer plates, reducing weight and providing a wider bearing surface for the Torlon® needle rollers. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners.

Fully machined Alloy cheek plates.

Head posts of swivel blocks can be locked at 0° or 90°.

Alloy sheaves with captive ball races.

Removable becket pin allows lines to be spliced prior to fitting.

Lashing

Lashing Orbit Blocks™ are a no-compromise product range with incredibly high breaking loads – up to 27,000kg – developed to meet the demands and expectations of the very dedicated and increasingly professional racing sailor. They are lightweight with a high strength-to-weight ratio, allowing for compact systems and significant weight savings. Versatile in many applications applications, the four lashing guide holes alloowing for multiple aattachment options including singgle, parallel and split lashingggs, and the central hole can be used for a becket in purchase systems. The two screew-togetther side cheeks incorporating the bbearing hub are precision machinedd from ssolid alloy, leaving materiaal only w where it contributes to the loaad carryying capacity of the blockk. The only fasteners used are for the gguide rollers near the head. The Orbit sheave runs on e extended d length Torlon® rollers with capptive ball bearings for side thrust loads, and is easilyy accessible for routine servicing. Every detail has beenn carefully executed to achhieve the best optimisation of pperformance, size, weeight and ultimate strrength available today.

ALL PURPOSE BLOCKS Ronstan’s all-purpose (AP) blocks are a great all around solution. Self-lubricating Acetal polymer sheaves running on polished Stainless Steel races perform equally well with dynamic loads and high static loads. For durability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising cru and racing. • Available in 40mm and 50m mm (19/16" and 2") sheave diameters to suit a range of rope p diameters and load requirements. • Smart Features™ like addjustable cleat arms and Captive Lock™ universal heads offer the same verssatility usually found only in ball bearing blocks. The comprehensive rangee of sizes and configurations offers solutions for every application.

Dynamic and High Staatic Load Performance UV stabilised Acetal sheaves proovide bearing performance on a polished Stainless Steel race that performs equally well with dynamic and static loads Sheave design features sidee ribs to minimise weight and enhance strength. Self-lubricating Acetal polymer minimises frriction and ensures dependable load bearing reliability.

Captive Lock™ Uniiversal Head A simple sliding lock that can be engaged to lock the head post in either of two planes, or disengaged to allow the bllock to swivel.

0°/90° 2-Axis S Shackle Head Some double and triple blocks can be locked at 0° or 90° by removing the shackle and changing the head post orientation.

Keyhole Beccket Pins Becket pins lockk into keyhole slots. No tools are required to remove the pins to fit pre-spliced liness or lock them back into place.

Adjustablle Cleat Arms The angle off the cleat arms can be adjusted easily. Sliding posts are simply pulled out of the sstops to adjust (no tools required), and then snap back into locked position too secure the arms.

BLOCKS™

Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal & aluminium sheave options, alloy cheeks and stainless fixings complete the durable ppackage. g For reliability aand a long service life, these blocks are the right choice forr sheets, halyardss and control line applica applications for cruisingg and racing. g

● ● Functionality ● Formal quality ● Ergonomics ● Durability ● Symbolic and emotive ● Self-explanation quality ● Ecological soundness

Stage 2 Stage 1

Rope

Wire Rope

Univerrsal B Bearing Dynamic aand hhigh static load pperformance The Ronstan Univversal B Bearing incorporates ourr proven 2-stage bearing system. Acetal Sheave

Stage 1 - Under moderate loadss, acetal ball bearings enssure minimum friction.

Alloy Sheave

Staage 2 - Under heavy loads, where deformation of baall bearings alone would result in increased friction, a slliding aacetal bearing on a polished stainless steel race takes over, maintaining low fricttion peerformance. Additionally the balll bearings are configured to acct as a thrust bearing between the sheave and chheeks, preventing the sheave frrom rubbing on the cheeks and causing fricttion w when the line lead in and oout of the block isn’t perfect. Particularly impportant for foot blocks.

Acetal & alum minium sheave ooptions Selected models are available with an alum minium sheave which has a deep groove proofile sppecifically made for use w with wire.

Aluminium m alloy cheek plaates Block cheekks are manufactured from m the highest quality aluminium alloy for maaximum strength. Materiaal optimisation and the cut-away desiggn minnimises weight and allow ws easy fresh water rinsing of salt andd debriis from the bearings. Chheek ddesign has been further sstyled with flaring at the block throat and redduced gap between the cheek and sheave, minimising rope wear, aand thee hollow hub can be usedd as a becket take-off or tie-up point.

Univversal head The head assembly incorporattes a brass bearing washer to providde smooth 360° rotation of the post and shackle. A set screw w arrangement allows thee head to be locked at 00° or 90°. 90 . S Shack les are high quality forgeed grade 316 stainless steel.

S Suits pre-spliced liness Rem movablle becket pins allow fittinng of pre-spliced lines. The flush fit beckeet pin hhead is kind on deck surfaces and won’t snag lines.

Fully articuulated stand-up Stand-up models have a low profile linkage that provides full rotation and articulation. A highh strenngth precision cast padeyye minimises the footprint and a dedicated rubber boot ennsuress the block is held upright when not loaded.
