Spinlock TSR30 – 5 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR30 5 Sheave Organiser offers increased capacity for diverting multiple high-load lines from clutches and jammers while maintaining efficiency and low friction. Featuring 30 mm alloy sheaves, the TSR30 handles large rope diameters and significant deflection angles reliably.
Sheaves rotate on plain bearings housed within a modular top rail, allowing custom spacing for optimal line separation. The tulip-shaped sheave design reduces friction during vertical movement, improving control and reducing rope wear. The low-profile TSR30L version suits installations where height is restricted, and fixed sheave inserts can be fitted to increase deflection load capacity.
