Product Details

Malleable iron C-clamp from TPMC is a pipe hanger component designed to attach securely to the bottom flange of I‑beams or wide‑flange beams without welding or drilling. A threaded hanger rod is threaded directly into the clamp body; after insertion, the rod end tightens against the flange to provide a centered load and a vibration‑resistant lock. It supports sprinkler piping, standpipe systems, conduit, cable trays, and other suspended mechanical services.
UL Listed and FM Approved, this clamp is suitable for fire protection systems, including sprinkler mains and standpipe risers, where reliable, heavy‑duty support is critical.
