Spinlock TSR20 – 4 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR20 4 Sheave Organiser delivers strong, precise line diversion in compact decks where multiple high-load lines need routing aft from clutches or jammers. Built with 20 mm alloy sheaves on plain bearings, it provides smooth and controlled deflection while withstanding significant working loads.
Its modular design allows sheaves to be repositioned to custom spacing, and the tulip-shaped sheave geometry minimises friction when lines experience vertical deflection. A low-profile TSR20L version is available for tight installations, while optional fixed sheave inserts further increase the allowable deflection loads.
