Ronstan is the only company that offers a 40mm ratchet block with both auto and manual engagement models.\u003c\/p\u003e\n\u003cp\u003eManual modes allow the ratchet mechanism to be switched on or off as required. This is the preferred mainsheet set-up for many top sailors.\u003c\/p\u003e\n\u003cp\u003eSelected Series 40 models.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAwesome ratchet block holding power\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eQuite 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmooth easing of sheets\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\u003cp\u003eLow profile stand-up kit allows 0° or 90° alignment\u003c\/p\u003e\n\u003cp\u003eStand-up kits feature a clatter-free rubber boot.
