Sandwich-Style High-Temp Round Duct Control

This Ductmate access door fits nominal duct diameters of 10 in and 11 in. It provides a rectangular opening 12 in wide by 8 in high for inspection or maintenance. The unit is rated for a maximum temperature of 300 degrees F. It is supplied new for HVAC system integration.

Verify Duct Diameter and Mounting Stud Length

Confirm your round duct measures either 10 in or 11 in nominal diameter before ordering. The door requires two mounting studs each 2 in long for secure attachment. Ensure the 22 ga material thickness suits the surrounding ductwork gauge. No hinge is included so the panel removes completely.

Thumbscrew Latches Enable Tool-Free Removal

Two thumbscrew latches hold the 1 1/8 in thick door panel without requiring tools for access. The steel observation port material allows visual checks while the door remains closed. Insulation material is not applicable and the assembly carries no fire rating. These features suit high-temperature duct servicing.
