HVAC Observation Access Door
The Ductmate GRDOI1612GA is a rectangular duct access door designed for HVAC system inspection. It fits nominal duct diameters of 7, 8 and 9 inches and provides a clear view through a 7 1/2 inch square observation port. The door measures 16 inches wide by 12 inches high with a 7/8 inch thickness.
Installation and Use Cases
This door suits technicians who need visual access to ductwork without removing panels. The fiberglass insulation and 22 gauge steel construction handle temperatures up to 200 degrees Fahrenheit. It is not intended for fire-rated assemblies or applications requiring a hinge mechanism.
Critical Specification
The rough opening must measure exactly 12 inches high to accept the factory‑supplied mounting studs. Two studs, each 2 inches long, secure the door to the duct wall. Verify this opening dimension before ordering to ensure proper fit.

Questions about this item
Will the fiberglass insulation need replacing after extended use at high temperatures?
The 22 ga steel door and fiberglass insulation are rated for continuous operation up to 200 Degrees F, so replacement is not expected under normal conditions.
What temperature limit stops the door from working safely during long runs?
The maximum temperature rating is 200 Degrees F; exceeding this could degrade the fiberglass insulation and the steel observation port.
How hot does the steel observation port get when the duct runs at the 200 Degrees F limit all day?
The 7-1/2 in steel observation port will reach the duct temperature, so at the 200 Degrees F rating it becomes too hot to touch without protection.
