Purlin clamp from TPMC is a specialized pipe hanger component designed for C-purlins and Z‑purlins. It attaches securely to the lower flange without the need to modify the purlin, accommodating both 45° sloped flanges and 90° flanges. 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 heavy‑duty clamp provides reliable attachment where standard beam clamps are unsuitable.

Available sizes
