Insulated Round Duct Access Door
The Ductmate GRDRI161232GA is a sandwich-style insulated access door for round HVAC ductwork. It fits nominal duct diameters of 29, 30, 31 or 32 inches and provides a 16 by 12 inch rectangular opening. Fiberglass insulation and a 7/8 inch door thickness help maintain thermal performance. The door is constructed from 20 gauge material with a maximum temperature rating of 200 degrees Fahrenheit.
Check Duct Diameter and Mounting Clearance
Verify that your existing ductwork matches one of the listed nominal diameters before ordering. The unit requires two mounting studs each measuring 2 inches in length for secure attachment. Ensure there is sufficient space around the duct for the rectangular door frame and knob latch operation. No hinge hardware is included, so plan for the door to be fully removable during access.
Replaces Uninsulated or Damaged Access Panels
This door upgrades older uninsulated panels or damaged units on 29 to 32 inch round ducts. The fiberglass insulation reduces thermal loss compared to non-insulated alternatives. The knob latch provides a tighter seal than simple friction-fit covers. The jump is worth it when energy codes require insulated access or when the existing panel no longer seals properly at temperatures up to 200 degrees Fahrenheit.
