Spinlock TSR20 – 7 Sheave Organiser (Standard and Low Profile)
The Spinlock TSR20 7 Sheave Organiser provides extensive capacity for diverting multiple high-load lines aft with reliable control and low friction. Designed around 20 mm alloy sheaves on plain bearings, it delivers strong, predictable performance for advanced rope layouts.
The modular assembly allows each sheave to be moved to any spacing along the alloy top rail, supporting custom line separation for dense configurations. The low-profile option facilitates installation in height-restricted areas, while fixed sheave inserts can be added to increase deflection load capability.
