The typical Open Arm configuration (CL-1000-PTC) offers a 92° arm opening and the option to adjust spindle location, while the related CL-1001-PTC provides a Solid Arm for fixed spindle placement. Construction details include a clamp body made from 1008/1010/1018 steel with a zinc-plated clear chromate finish, a steel/aluminum air cylinder, and 400-series stainless rivets, all designed for Durability in manufacturing fixtures. The unit is manufactured in the USA and weighs about 3.0 lbs in shipping.
