S-5-H Clamp

The S-5! H Clamp is engineered for metal roof panels with horizontal seams that are not fully closed. Its two-piece body allows the clamp to be installed anywhere along the seam’s length. Setscrews are side-installed for grip, and a top M8 bolt is provided for attaching ancillary equipment. The H Clamp works in heavy-duty applications including snow retention systems like ColorGard, PV installs, signage, conduit and more. A Mini version is available for lighter applications under lower loads.

Key Features:
