Series 40 Ratchet Orbit Block™ - Single - Auto - Swivel Shackle HeadAutomatic RatchetWith automatic models, 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.Awesome Ratchet Block Holding PowerQuite simply, Ronstan Ratchet Orbit Blocks™ have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power, almost double that of our nearest competititor.The unique sheave design has 8 gripping faces which directly resist loaded line movement. Traditional designs have an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.Simple and Secure AttachmentThe Dyneema® 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 shackle pins.The system is compatible with Dyneema®/Spectra® strops, webbing and carbon connection points - much more so than steel loop tops or shackles.Smooth Easing of SheetsWith auto models the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages. Low Profile Stand-Up Kit Allows 0™ or 90™ AlignmentStand-up kits feature a clatter-free rubber boot. You can attach the Dyneema® link so that the block is aligned with the stand-up base or across it. It's a neat low-profile solution which allows full articulation.Features: Up to 14:1 holding power - highest available! Smooth easing of sheets Fully Automatic load sensing ratchet engagemen Swivel shackle head for unlmited block rotation Stainless steel shackle head for ultimate durability and compatibility with harsh fixing points Applications: Dinghy mainsheet systems Mainsheet fine tune systems on sportsboats & small keel boats Mainsheet systems on sportsboats using RF7 mainsheet swivel cleat unit Spinnaker and job sheets on dinghies - especially modern asymmetric classes Control line applications on larger yachts Materials: Sheave: Hard anodised Aluminium Ball Bearings: High compression strength carbon black Acetal Frame/Cheeks: Toughened, glass fiber reinforced Nylon Rope Link: UV stabilized, multi-strand impregnated SK75 Dyneema® Specifications:Sheave Ø: 40mm(1-9/16")Max.

Series 40 Ball Bearing Orbit Block - Single - Becket - Cleat - Swivel HeadFeatures: Ultra Lightweight Low friction 2-stage Orbital ball bearing system Highest working load in its class Low profile and compact High performance cleating LightweightKilogram for kilogram of working load, BB and RT Orbit Blocks™ are the world’s lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimizes the mass of the inactive return race and hub.Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.Highest Working Load In It's ClassThe orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximizes load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.The floating sheave and bearing system is supported by a fiber-reinforced load frame. The design was computer modeled to be stress optimized.Applications: Mainsheet systems on spinnaker sheet on dinghies to 5m (16ft) Spinnaker sheets on dinghies, sportsboats and small keel boats to 5m (16ft) Halyard, vang and backstay applications on boats to 8m (26ft) Control line applications on larger yachts Materials: Ball Bearings - High compression strength carbon black Acetal. Stage 2 Bearing - Glass fibre reinforced, MoS2 impregnated Nylon Frame/Cheeks - Toughened, glass fibre reinforced Nylon Sheave - Carbon fiber reinforced, PTFE impregnated Nylon
