Wire Exit Sheave Box

Description

Wire Exit Sheave Box

This wire exit sheave box has been designed specifically for use with wire halyards. The large opening on one side of the sheave allows a wire ferrule to pass over the sheave and into the mast, perfect for jib halyards when the tail would typically be spliced onto an eye in the wire.

With an easy to remove axle pin, sheaves can be maintained or swapped very simply. The axle pin is held in place by the surface the box is mounted too or the curved backing plate which is included.
