Square duct access door

Technicians needing fire-rated access should look

This door carries no fire rating and is limited to a maximum temperature of 175 degrees Fahrenheit. Installers who require a rated assembly or higher temperature tolerance must select a different model.

Holds shape under continuous heat

The 24 ga steel frame and fiberglass insulation maintain integrity at the rated 175 degree limit during sustained operation. The double cam latch keeps the door firmly seated through thermal cycling and vibration.
