Ductmate 12 in access door
The Ductmate GRD1010ULBI is a square duct access door measuring 12 in by 12 in. It is built from 11 ga steel with a 1/2 in door thickness and carries a maximum temperature rating of 300 Degrees F. Installers use it to create inspection or service openings in HVAC ductwork.
Thumbscrew latch for tool-free entry
The door secures with thumbscrew latches so panels can be opened and closed without tools. Two mounting studs, each 1 1/2 in long, anchor the frame to the duct. No hinge is included, so the panel lifts completely away for full clearance.
Uncoated steel suits dry indoor runs
The uncoated finish is intended for standard indoor duct systems where corrosion exposure is low. It handles temperatures up to 300 Degrees F, making it suitable for supply and return air streams. The door has no fire rating and no observation port, so it does not meet rated-barrier or visual-inspection requirements.

Questions about this item
How does the 12-inch square opening affect airflow access in a real duct run?
The 12 by 12 inch square door provides a full-sized inspection and cleaning port that matches standard rectangular duct dimensions, allowing tools and vacuum hoses to enter without restriction.
What does the 11-gauge steel thickness and 300-degree rating cap in practice?
The 11-gauge steel construction withstands continuous temperatures up to 300 degrees Fahrenheit, making the door suitable for high-heat supply ducts while maintaining structural rigidity under pressure.
What do the two 1-1/2 inch mounting studs and thumbscrew latches require for installation?
Two 1-1/2 inch studs anchor the frame to the duct wall, and the thumbscrew latches secure the door panel by hand — no tools needed for routine access once the frame is fastened.
