Harken 178mm Narrow Halyard & Steering Sheave
Harken's 178mm Narrow Halyard and Steering Sheave is made to handle high-load masthead and steering applications requiring line or wire.
The sheave improves sail handling, speeds up sail changes, and allows the use of smaller, lighter halyard winches.
Used in steering systems, it returns feel and sensitivity to helms with wheels.
The sheave combines sideload-carrying balls with PTFE composite bushing for radial loads.
