  • Fits 12, 13 and 14 in round duct sizes
  • Withstands 300 °F for high-temperature applications
  • 22 ga steel construction resists deformation
  • Thumbscrew latches allow tool-free access
  • Two 2 in mounting studs secure the door

Duct Access Door 8 in x 4 in

This rectangular duct access door measures 8 inches wide by 4 inches high with a 1 1/8 inch thickness. It is constructed from 22-gauge steel and carries a maximum temperature rating of 2,300 degrees Fahrenheit. The unit mounts with two 2-inch studs and secures via thumbscrew latches.

For round duct inspection and cleaning

The door fits nominal duct diameters of 12, 13 and 14 inches, making it suitable for technicians who need periodic access to round ductwork. It has no hinge or observation port, so installers who require a hinged cover or a built-in viewing window should consider a different style.

2,300 °F maximum temperature rating

This single specification determines whether the door can withstand the heat present in the system. Verify that the operating temperature of the duct never exceeds this limit before installation.

Questions about this item

How do I install the Ductmate 8414F2GA access door on a round duct, and what step is often missed?

Cut an opening matching the 8 in by 4 in door size, position the frame against the duct wall, and secure it with the two 2 in mounting studs using the thumbscrew latches; the step often missed is verifying the duct diameter is 12, 13, or 14 in before cutting.

What maintenance or replacement will the Ductmate 8414F2GA need over time?

Inspect the steel observation port and 22 ga frame periodically for corrosion or heat distortion; replace the door if the thumbscrew latches no longer hold the 1 1/8 in thick panel tightly against the duct.

What is the first limit reached when the Ductmate 8414F2GA is used continuously at high temperature?

The 300 degrees F maximum temperature rating is the primary limit; sustained exposure above this can degrade the steel door and frame before any other component fails.
