SENQCIA Inspire Series Double Capacity Riveted roller chains are manufactured and possess twice the number of link plates and therefore twice the ultimate strength of standard single strand roller chain. These chains possess solid bushings and rollers and operate on standard ASME/ANSI single strand sprockets. They are primarily designed for high load hoist, pull down, or other tension linkage applications. They may also operate successfully on low speed – high load drives. Packaged chains are supplied with a necessary connecting link to join the ends. Offset links are not available for Double Capacity chains. This chain is packaged in a 10ft box.
