12×8 in duct access door
The Ductmate GRDR12816F2GA is a rectangular steel access door sized 12 by 8 inches with a 1 1/8 inch panel thickness. It fits nominal 15 and 16 inch round duct and carries a 300 °F maximum temperature rating. Two 2-inch mounting studs secure the door with thumbscrew latches.
Installers needing high-temp rectangular entry
Technicians who require a 300 °F rated rectangular opening on 15 or 16 inch round duct will find this door suitable. Buyers who need a fire-rated assembly, an observation window or a different door size should look at other options. The unit ships without hinge hardware.
300 °F temperature rating
The single specification that decides fit is the 300 °F maximum temperature rating. If the duct system operates above this limit the door cannot be used. All other dimensions and mounting details follow from the 12×8 inch rectangular cut-out and the two 2-inch studs.

Questions about this item
What duct diameter must the opening fit for this 12×8 in access door?
The door is sized for nominal duct diameters of 15 in and 16 in, so the cut opening must match one of those round ducts.
Will the 2 in mounting studs reach through my existing duct wall?
Two 2 in mounting studs are supplied; they suit standard duct wall thicknesses, but verify your wall depth before installation.
How can I confirm the latch is holding at the rated 300 °F limit?
Tighten both thumbscrews fully — the steel observation port and 22 ga frame are rated to 300 °F, so a secure latch indicates proper engagement.
