Spinlock TSR20 – 9 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR20 9 Sheave Organiser supports complex, high-load line systems where many lines must be routed aft from clutches and jammers. Using 20 mm alloy sheaves with plain bearings, it offers smooth, predictable performance under high working loads.
The modular top rail allows sheaves to be re-spaced to achieve exact line separation, while the tulip-shaped geometry reduces friction during vertical deviations. A standard and a low-profile version are available, and fixed sheave inserts can be added to increase the allowable deflection loads.
Key Features
• Nine 20 mm alloy sheaves
• Engineered for high-load line diversion aft
• Adjustable sheave spacing via modular system
• Tulip profile reduces vertical friction
• Standard and Low Profile models
• Optional fixed sheaves for higher deflection loads
• Endless line compatible
• Titanium upgrades available
• Custom spacing on request
