Complementary Hardware > Narrow Halyard & Steering Sheaves
Narrow high load sheaves in mastheads improve sail handling, speed sail changes, and allow the use of smaller, lighter halyard winches. Used in steering systems, these sheaves return "feel" to wheel-steered boats.
Sheaves combine sideload-carrying balls with a Teflon® composite bushing for radial loads. These durable sheaves are made of 6061-T6 aluminum and are well suited to masthead and steering installations.
Installation requires clamping or securing inner race.
