18-inch square access door

The Ductmate GRFDH18GA is a square duct access door measuring 18 inches high by 18 inches wide. It provides an inspection or service opening in rectangular ductwork for HVAC technicians and sheet-metal installers. The door panel is transparent and includes 2-inch mounting studs for tab-in installation.

175-degree temperature limit

The assembly is rated for a maximum operating temperature of 175 degrees Fahrenheit. Fiberglass insulation is built into the 2 1/8-inch thick door panel. No fire rating is assigned, so the door must not be used where a listed fire damper or rated access panel is required by code.

24-gauge steel with single-cam latch

The frame and door are constructed from 24-gauge steel with a single cam latch to hold the panel closed. Tab-in hinge tabs fold into the duct opening for a secure mount without separate fasteners. An integrated steel observation port allows visual checks without fully opening the door.

Questions about this item

Which duct access door size matches my 18-inch duct opening?

The GRFDH18GA provides an 18-inch by 18-inch square opening with a 2 1/8-inch thick insulated door that fits the same nominal dimensions.

What does the 175-degree Fahrenheit temperature rating mean for daily operation?

The fiberglass-insulated door assembly is tested to withstand continuous air-stream temperatures up to 175 °F without degradation.

How does the tab-in hinge and single-cam latch limit installation options?

The tab-in hinge requires a prepared slot in the duct wall and the single cam latch secures from one side only, so access must be planned accordingly.
