Harken 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 for
masthead and steering installations.
Installation requires clamping or securing inner race.
