H-Loc™ Open Hem Gambrel

The H-Loc™ Open Hem Gambrel is a precision-formed transition trim designed to finish and protect the change in roof slope on gambrel-style metal roofs. Installed at the pitch break where upper and lower roof panels meet, it covers panel edges while directing water away from the joint — creating a clean, weather-resistant transition.

Formed from durable galvanized steel and matched to Central States H-Loc™ panel geometry, the open hem design provides a straight, finished edge that improves appearance and helps prevent water, debris, and pest intrusion at this critical roof transition.
