Spinlock TSR30 – 3 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR30 3 Sheave Organiser is a heavy-duty aft organiser designed for diverting multiple high-load lines from clutches and jammers with maximum control and low friction. Using robust 30 mm alloy sheaves on plain bearings, the TSR30 delivers predictable high-load performance for applications where larger rope diameters, significant deflection angles, or elevated working loads are involved.
The modular alloy top rail allows each sheave to be repositioned to achieve custom spacing, supporting dense line layouts on larger performance yachts. The tulip-shaped sheave profile reduces friction during vertical deflection, while optional fixed sheave inserts increase permissible deflection loads. The TSR30L low-profile version suits installations with restricted height such as mast bases and in-deck tunnels.
