Spinlock TSR20 – 5 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR20 5 Sheave Organiser is a modular, high-load aft organiser designed to handle multiple control lines requiring reliable deflection from clutches or jammers. Featuring 20 mm alloy sheaves with plain bearings, it provides strong, predictable line handling for performance-focused yachts.
The modular assembly allows repositioning of sheaves along the alloy top rail, enabling custom spacing for dense rope layouts. The tulip-shaped sheave design reduces friction when lines experience vertical deviation, improving control and reducing wear. Standard and low-profile versions accommodate a wide range of installation constraints.
Key Features
• Five 20 mm alloy sheaves
