The CT Crimpers require no booster or intensifier which means they can be operated directly from the hydraulic circuits already installed on line trucks, dedicated power units, or from one of the STANLEY portable Power Units. The CT10 has a 1 in or 1.5 in C-type head, depending on model. It accepts industry-standard U style dies, and has a capacity of up to 750 MCM copper cable, depending on model.
