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.
