Ductmate 16×16 Cammed Access Door

This square HVAC access door measures 16 inches wide by 16 inches high and is built from 24-gauge steel with a transparent finish. A double-cam latch secures the panel while a tab-in hinge allows the door to swing open for duct inspection or cleaning. Fiberglass insulation lines the 2 1/8-inch-thick frame to reduce thermal loss.

Suited for technicians needing tool-free entry

Installers who want quick, repeatable access to rectangular ductwork will appreciate the cam latch that tightens by hand. The door carries no fire rating and is limited to a maximum temperature of 175 degrees Fahrenheit, so it is not appropriate for fire-rated assemblies or high-heat exhaust systems.

Holds seal under continuous cycling

The double-cam mechanism maintains consistent compression on the gasket during repeated open-close cycles, preventing leakage when the system pressurises and depressurises. Fiberglass insulation retains its thickness under sustained operating temperatures, so thermal performance remains steady throughout long heating or cooling seasons.

Questions about this item

What duct dimensions do I need for the 16 in by 16 in access door?

The door requires a 16 in wide by 16 in high square opening in the ductwork. The frame adds a 2 1/8 in thickness and includes 2 in mounting studs for securing it to the duct.

Will the double-cam latch hold tight on an existing 24 ga duct that flexes slightly?

Yes, the double-cam latch is designed for 24 ga metal and the tab-in hinge allows the door to seal evenly even if the duct has minor movement or vibration.

How can I confirm the fiberglass insulation is intact after installation?

Open the door and visually inspect the transparent panel; you should see the fiberglass layer behind it without gaps or compression, and the door should close flush with both cams engaged.
