Sea-Dog Stainless Steel Chain Stopper – 5/16″ – 3/8″

Product Overview

When servicing or upgrading marine hardware, electrical, plumbing and boat outfitting, Stainless Steel Chain Stopper – 5/16" – 3/8" is intended to handle servicing or upgrading marine hardware, electrical, plumbing and boat outfitting while matching the relevant installation or operating requirements.

Chain Stoppers help prevent damage to the windlass and reduce the risk of accidental free fall of the anchor while under way. Chain Stoppers mount alone or inside most bow rollers and work with your anchor roller to take tension off your windlass. Chain and rope should be secured at anchor when your windlass is not in use to avoid high loads the windlass was not engineered for.
