Description
Sea-Dog Stainless Steel Chain Stopper - 3/16" - 1/4" [321820-1]Stainless Steel Chain Stopper 3 16" 1 4" 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 designed for. 321820 fits chain sizes 3 16" 1 4".

Good bang for your buck, great quality.
Works great. Most of it is metal and works as a heat sink. Came with two fuses and the adapters for smaller or larger Guage wires. Fit very well and easily for our choice of installation and was a great price.

Good for under the hood
Pretty good heavy duty block. It's got the rubber grommets for the smaller wire if needed.
