Constructed with precision-molded acetal sheaves running on stainless steel ball bearings, this block ensures low friction and smooth operation even under demanding conditions. Its compact design features a four-point fastening system for optimal load distribution and a low profile, allowing easy mounting without disassembly. The inclusion of an O-ring in the single loop head blocks helps to keep the running line separate from head lashing or fixing, enhancing reliability and ease of use. Built for durability, the sheaves are made from UV-stabilized acetal, while the cheeks are crafted from Grade 316 stainless steel, providing corrosion resistance in marine environments. The stainless steel ball bearings further contribute to longevity and high performance. This utility block is well-suited for applications such as dinghy control lines, vang, Cunningham, and tweaker systems, as well as shock cord tensioning setups. Its compact size and robust materials make it an ideal choice for sailors and riggers seeking a lightweight yet durable solution for their control systems. Whether installed on small boats or intricate rigging setups, the Ronstan Series 15 utility block delivers reliable performance and ease of installation, all while maintaining a minimal weight footprint.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eSmallest and lightest ball bearing utility block available for lightweight applications\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\u003eFour-point fastening system provides excellent load distribution and a low profile design\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMountable without disassembly for quick installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable materials: UV stabilized acetal sheaves, stainless steel ball bearings, and Grade 316 stainless steel cheeks\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIdeal for dinghy control lines, vangs, cunninghams, tweakers, and shock cord tensioning systems\u003c\/li\u003e\u003c\/ul\u003e","brand":"Ronstan","offers":[{"title":"Default Title","offer_id":44530217517098,"sku":"71025","price":40.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/71025XL.jpg?v=1783113204","url":"https:\/\/atticusgoods.com\/products\/ronstan-series-15-ball-bearing-utility-block-pivoting-lead-block-with-stainless-steel-components","provider":"Atticus Goods","version":"1.0","type":"link"}
