The Chain Sock is constructed from a hard wearing knitted polyester blend designed to cover 6mm short link chain. Bright fluro green colour is designed to provide a visual warning when anchor is approaching the bow roller, especially at night. Helps prevent damage to gelcoat and gunwales when anchor chain is fed out or retrieved plus reduces bottom bounce noise which may scare off fish. Sold in 8 metre lengths to suit 6mm short link chain.
