Extra Capacity Chains Double Capacity Roller Chains Double Capacity roller chains possess twice the number of link plates and therefore twice the ultimate strength of standard single strand roller chains. They are primarily designed for high load hoist, pull down, or other tension linkage applications, and operate on standard ASME/ANSI single strand sprockets with hardened teeth. Multiple strand Double Capacity chains are not available.
