Abstract
Abstract A cover for a capstan type winch comprises a blind tie-down cord which encircles the spool of the winch and threads through ears extending inwardly from the inner wall of the cover. The cord acts to hold the cover in place when tensioned and tied. A series of axially disposed ribs extending inwardly from the cover wall near the top yieldably engage the spool at the top and accommodate the cover for use with winches of different sizes.
