The NC-machined sheave features Generation 2 of Ronstan's patented cross-hole geometry, providing eight gripping faces that resist loaded line movement effectively. This design minimizes rope wear by drawing the rope into the gripping area under load.\u003c\/p\u003e\u003cp\u003eThe block ensures smooth easing of sheets, with automatic models allowing the sheet to run out smoothly when the ratchet mechanism disengages. The sheave's cross-hole geometry eliminates the 'shuddering' ease-out found in traditional v-groove ratchet blocks.\u003c\/p\u003e\u003cp\u003eFeatures include clockwise rotation, fully automatic load sensing ratchet engagement, and a recessed underside for curved mounting surfaces. It is ideal for dinghy mainsheet systems, mainsheet fine-tune systems on sportsboats and small keel boats, and control line applications on larger yachts.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eB.L.
