Access door for 12×8 ductwork

This steel access door fits a 12-inch-wide by 8-inch-high rectangular opening in HVAC ducting. It installs with two 1½-inch mounting studs secured by thumbscrew latches. The door panel is 11-gauge steel and carries no fire rating.

Technicians adding inspection points

Installers who need a quick-entry port for damper adjustment, sensor placement or duct cleaning will find the tool-free thumbscrews practical. Projects that require a fire-rated assembly or an insulated panel should select a different model.

11-gauge steel construction

The door panel uses 11-gauge steel and is rated for continuous exposure up to 2,300 °F. That thickness and temperature limit are the primary factors in deciding whether the door meets the mechanical and thermal demands of the system.
