Its primary benefit is a durable lightweight lead for up to 8mm (5\/16\") rope providing secure handling with minimal bulk.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e30mm x 12mm sheave suitable for up to 8mm rope\u003c\/li\u003e\n\u003cli\u003eInternal steel frame for increased strength at 88g weight\u003c\/li\u003e\n\u003cli\u003eSwivel head plus fixed becket for single-line attachment and easy re-leads\u003c\/li\u003e\n\u003cli\u003eRated SWL 355kg with break load 710kg for verifiable strength\u003c\/li\u003e\n\u003cli\u003eDouble sheave supports simple purchase systems and tandem leads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProblem\/solution: when deck space and weight matter you need compact hardware that still carries measured loads. This block solves that by combining double plain-bearing sheaves and a becket in a 93 x 40 x 32 mm unit so you can reroute or lead lines without extra fittings.\u003c\/p\u003e\n\u003cp\u003eCompared to ball-bearing variants this plain bearing model is simpler and lower maintenance; Barton also offers ball-bearing sheave options where higher rolling efficiency and higher rolling-load ratings are required. Use this block for halyards, reefing lines, small mainsheet leads, and light purchase systems on dinghies and cruising boats.\u003c\/p\u003e\n\u003cp\u003eTrust signals: built with an internal steel frame by Barton Marine and supplied as part number N01231 with published SWL and break-load figures.
