Its compact size makes it the smallest and lightest ball bearing block available, ideal for use in dinghy control lines, vangs, cunninghams, and shock cord tensioning systems. The precision-molded acetal sheave runs smoothly on stainless steel ball bearings, offering low friction and efficient operation, even under demanding conditions. The single loop head block features an integrated O-ring that separates the running line from head lashing or fixing points, simplifying installation and enhancing reliability. Its flush rivet design minimizes cutout and ensures a seamless profile, reducing wear and facilitating maintenance. The formed single-piece housing provides maximum strength while minimizing rope wear, contributing to durability and consistent performance over time. Made with UV-stabilized acetal sheaves, stainless steel ball bearings, and Grade 316 stainless steel cheeks, this utility block is built to withstand harsh marine environments. Whether used for control lines on small sailboats or tensioning systems on larger vessels, the Ronstan Series 15 offers a robust, lightweight solution for demanding sailing applications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eSmallest and lightest ball bearing block available\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePrecision molded acetal sheave running on stainless steel ball bearings for high performance and low friction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSingle loop head blocks include an O-ring to separate running line from head lashing or fixing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFlush rivet design minimizes cutout and facilitates installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFormed single-piece housing for maximum strength and minimal rope wear\u003c\/li\u003e\u003c\/ul\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":44530215813162,"sku":"71031","price":34.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/71031XL.jpg?v=1783113087","url":"https:\/\/atticusgoods.com\/products\/ronstan-series-15-ball-bearing-utility-block-exit-block-part-number-rf15711","provider":"Atticus Goods","version":"1.0","type":"link"}
