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\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 14:1 holding power - highest available.\u003c\/li\u003e\n\u003cli\u003eSmooth easing of sheets\u003c\/li\u003e\n\u003cli\u003eClockwise rotation.\u003c\/li\u003e\n\u003cli\u003eFully automatic, load sensing ratchet engagement.\u003c\/li\u003e\n\u003cli\u003eRecessed underside to suit curved mounting surface.\u003c\/li\u003e\n\u003cli\u003eLow mounting points for maximum strength.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMax.
