Ronstan is the only company that offers a 40mm ratchet block with both auto and manual engagement models (on selected Series 40 models). \u003cbr\u003e\u003cbr\u003e With 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. \u003cbr\u003e\u003cbr\u003e Manual modes allow the ratchet mechanism to be switched on or off as required. This is the preferred mainsheet set-up for many top sailors. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAwesome ratchet block holding power\u003c\/strong\u003e\u003cbr\u003e Quite simply, Ronstan Ratchet Orbit Blocks„¢ have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our patented sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power, almost double that of our nearest competititor. \u003cbr\u003e\u003cbr\u003e 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. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSimple and secure attachment\u003c\/strong\u003e\u003cbr\u003e The 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. \u003cbr\u003e\u003cbr\u003e The system is compatible with Dyneema®\/Spectra® strops, webbing and carbon connection points - much more so than steel loop tops or shackles. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSmooth easing of sheets\u003c\/strong\u003e\u003cbr\u003e With auto models the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages. When engaged, and with manual models, the sheave cross - hole geometry eliminates the 'shuddering' ease-out that you can expect from traditional v-groove ratchet blocks. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eLow profile stand-up kit allows 0° or 90° alignment\u003c\/strong\u003e\u003cbr\u003e Stand-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. \u003cbr\u003e\u003cbr\u003e\u003cspan class=\"subtitles_red\"\u003eApplications\u003c\/span\u003e\u003cbr\u003e\u003cli\u003eDinghy mainsheet systems\u003c\/li\u003e\n\u003cli\u003eMainsheet fine tune systems on sportsboats \u0026amp; small keel boats\u003c\/li\u003e\n\u003cli\u003eMainsheet systems on sportsboats using RF7 mainsheet swivel cleat unit\u003c\/li\u003e\n\u003cli\u003eSpinnaker and job sheets on dinghies - especially modern asymmetric classes\u003c\/li\u003e\n\u003cli\u003eControl line applications on larger yachts\u003c\/li\u003e\n\u003cspan class=\"subtitles_red\"\u003eMaterials\u003c\/span\u003e\u003cbr\u003e\u003cli\u003eSheave: Hard anodised Aluminium\u003c\/li\u003e\n\u003cli\u003eBall Bearings: High compression strength carbon black Acetal\u003c\/li\u003e\n\u003cli\u003eFrame\/Cheeks: Toughened, glass fibre reinforced Nylon\u003c\/li\u003e\n\u003cli\u003eRope Link: UV stabilised, multi-strand impregnated SK75 Dyneema®\u003c\/li\u003e\n\u003c\/div\u003e\n\u003c!-- FIN SCRIP PANLS--\u003e\n\u003c\/div\u003e","brand":"Ronstan Sailboat Hardware","offers":[{"title":"Default Title","offer_id":53594377159028,"sku":"RONRF46151A","price":77.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/4004\/9524\/files\/RONRF46151A-2__30399.jpg.1428984928.jpg?v=1761730361","url":"https:\/\/velasailingsupply.com\/products\/ronstan-series-40-rta-orbit-block-cheek-anti-clockwise-rotation","provider":"Vela Sailing Supply","version":"1.0","type":"link"}
