22×22-inch access door for ductwork
The Ductmate GRFDC22GA is a square duct access door measuring 22 inches wide by 22 inches high. It is built from 24-gauge material with a 2 1/8-inch thick fiberglass-insulated panel and a transparent observation port. The unit is designed for technicians who need a fire-rated opening up to 175 degrees Fahrenheit in commercial or residential HVAC systems.
Tab-in hinge and double-cam latch
Installation uses a tab-in hinge style that slides into the duct opening and secures with a double-cam latch mechanism. The door includes mounting studs measuring 2 inches in length for fastening. A common issue is misaligning the tab hinges during insertion, which prevents the cams from engaging fully and leaves an air gap.
Sustained heat and pressure performance
The fiberglass insulation and 24-gauge steel construction maintain integrity at the rated 175-degree maximum temperature during continuous system operation. The double-cam latch holds the door firmly against duct pressure over long cycles without loosening. The transparent port allows visual inspection without opening the door, preserving the seal under sustained load.

Questions about this item
How do I confirm the access door is sealing properly after installation?
Verify the double cam latches engage fully and the tab-in hinges hold the 22 in square panel flush against the duct; the 175 °F maximum temperature rating applies only when the door is closed and latched.
What components are included with the GRFDC22GA and what must be sourced separately?
The door assembly with fiberglass insulation, double cam latches, tab-in hinges and 2 in mounting studs is supplied; fasteners for attaching the studs to the ductwork are not included.
Which cam-latch version of the 22x22 in access door should I choose?
The GRFDC22GA is the double-cam model in 24 ga steel with a 175 °F rating; no other latch style or gauge is offered for this size in the product line.
