Thomas & Betts AC28 Conduit Clamp Box Connection (AC28 PLM, 3-inch conduit) is a clamp‑style fitting that attaches a 3-inch conduit to a metal electrical box, providing a secure, mechanical termination for conduit entering an enclosure. This model is part of the Thomas & Betts conduit fittings lineup (now ABB) and is designed for standard commercial and industrial installations where a 3-inch conduit terminates in a box, delivering a stable interface between conduit and enclosure to help maintain alignment and enclosure integrity.
