Spinlock TSR20 – 10 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR20 10 Sheave Organiser is the highest-capacity TSR20 model, designed for yachts requiring very large numbers of high-load line diversions from clutches and jammers. Featuring 20 mm alloy sheaves and a fully modular rail system, it allows complete customisation of sheave spacing and configuration.
The tulip-shaped sheave profile reduces friction during vertical movement, improving fairness and line longevity. The TSR20L low-profile version suits installation zones with tight vertical clearance, while fixed sheave inserts can be added to increase permissible deflection loads for extreme applications.
