The Carlon Handy Box is a nonmetallic switch and outlet box specifically designed for use with nonmetallic conduit systems and nonmetallic sheath cabling. Unlike metal boxes, the Carlon Handy Box has two integral cable clamps. These clamps hold nonmetallic cable firmly in place without the need for separate clamps... simply push the wire into the clamp-opening, and the cable is held securely in place.
