24-by-24-inch cammed access door

The Ductmate GRFDC24GA is a square duct access door measuring 24 inches wide by 24 inches high. It is designed for HVAC professionals who need reliable entry to rectangular ductwork for inspection or maintenance. The unit features a double-cam latch mechanism and a tab-in hinge style for secure attachment. Its fiberglass insulation helps maintain thermal integrity inside the duct system.

Sustained heat resistance up to 175 degrees

The door carries a maximum temperature rating of 175 degrees Fahrenheit, allowing it to remain stable during continuous warm-air handling. The 24-gauge metal construction combined with the fiberglass core resists warping under prolonged thermal cycling. The double-cam latch maintains a tight seal even when the duct expands and contracts with temperature changes. No fire rating is assigned, so the door suits standard ventilation rather than rated fire barriers.

Transparent panel with two-inch mounting studs

The transparent panel material lets technicians visually confirm damper position or debris buildup without opening the door. Each unit includes mounting studs that are two inches long, simplifying installation through the duct wall. The tab-in hinge allows the door to swing clear for full access while remaining captive. The 2-1/8-inch overall thickness fits flush within typical duct insulation blankets.

Questions about this item

How much heat can the 175-degree cammed door handle during continuous HVAC operation?

The door carries a maximum temperature rating of 175 degrees Fahrenheit, so it remains stable when the duct runs at that temperature all day.

Does the 24-inch square frame require any special duct preparation before the cammed door fits?

The door is designed for a 24 by 24 inch opening and uses tab-in hinges with double-cam latches that secure directly to standard ductwork.

Will the fiberglass-insulated 24-gauge door seal against an older uninsulated metal duct?

The built-in fiberglass insulation and double-cam latch create a tight seal even when mated to older, uninsulated duct sections.
