More strength with lower weight makes G43 High Test chain popular for boats with electric windlasses.An excellent choice for ground tackle, Grade 43 chain is about 35% stronger than conventional BBB chain, which allows you to save weight without sacrificing anchoring security.In the hot-dip process, this chain is specially shot-peened before galvanizing to create long-lasting protection against corrosion. It comes with a two-year guarantee against rusting and is made in the U.S. out of high-carbon steel so it resists wear, making it a good choice for abrasive anchoring situations. With links slightly longer than BBB, it is the chain specified for use with many of the windlasses sold by West Marine. We sell Acco chain by the foot in lengths up to the size of the standard pack.
