Square Access Door for 20 in Duct Openings

The Ductmate GRFDH20GA is a square access door designed for 20 in by 20 in duct openings. It uses a tab-in hinge style that fits directly into the ductwork without separate framing. The door panel includes fiberglass insulation material and a single cam latch for secure closure. It serves technicians who need regular entry for inspection, cleaning or damper adjustment.

Fire Rating Not Rated With 175 °F Temperature Limit

The door carries no fire rating and has a maximum temperature rating of 175 °F, so it suits general ventilation and low-temperature exhaust systems. Its 24 ga steel construction and 2 1/8 in panel thickness provide rigidity while keeping the assembly light. The transparent finish allows quick visual checks of the interior without opening the latch.

Sustained Heat Up to 175 °F Without Warping

Under continuous exposure to the rated 175 °F the insulated panel and steel frame maintain their shape and the cam latch remains operable. The tab-in mounting studs hold the door firmly in place through repeated thermal cycles. Systems that regularly exceed this temperature will need a higher-rated alternative.

Questions about this item

How do I install the tab-in hinge on a 20 in duct opening?

Fit the 2 in mounting studs through the duct wall, then snap the tab-in hinge legs into the slots until they lock; the common mistake is not seating both tabs fully before tightening the single cam latch.

What maintenance will the fiberglass insulation and cam latch need over time?

Inspect the fiberglass insulation for compression or moisture damage annually and lubricate the single cam latch pivot if it begins to bind during operation.

At what temperature does the 24 ga steel door reach its limit during sustained heat exposure?

The maximum temperature rating is 175 Degrees F; sustained operation above this level can degrade the fiberglass insulation and warp the 24 ga steel panel.
