The FORESPAR Mast Light Chafe Guard for ML-2 keeps lines from snagging while protecting fittings. This protects your lines from wear and tear and your light from damage, or even being pulled off the mast by a loaded halyard. Also adds extra safety by eliminating any unnecessary problems with lines getting caught. Mast Light Chafe Guard will also work with the Aqua Signal Model 254047-7 Combo Light.
