Grade 1 Heavy Duty Commercial Door Closer Included

This Steel-Lite 180 minute fire rated hollow metal door package includes a Grade 1 heavy duty commercial door closer with regular arm.

The included commercial door closer helps the door close smoothly after each use while reducing wear on the door, welded frame, hinges, and locking hardware.

Why This Fire Rated Package Stands Out

This is not just a hollow metal door slab. It is a complete 180 minute fire rated commercial door package designed around a UL listed flush steel door and UL listed welded hollow metal frame. By combining the fire rated door, 3 hour rated welded frame, Grade 1 heavy duty commercial door closer with regular arm, ball bearing hinges, Grade 1 commercial lever lock, ADA saddle threshold, bottom brush sweep, screw-on frame gasket, and mounting hardware into one matched package, Steel-Lite helps simplify ordering and reduce the risk of missing, incorrect, or incompatible parts.

For contractors, maintenance teams, and property managers, this means fewer purchase orders, fewer product compatibility questions, and a cleaner, more professional finished exterior fire rated opening.
