Duct Access Door for 12-14 Inch Ducts

This rectangular steel access door fits nominal duct diameters of 12, 13 and 14 inches. It provides a secure entry point for inspection or maintenance inside high-temperature round ductwork.

Maximum Temperature Rating 300 Degrees F

The door withstands continuous exposure up to 300 degrees Fahrenheit, making it suitable for high-temperature HVAC systems. Builders needing a higher fire rating or higher temperature limit must select a different component.

Thumbscrew Latches and Mounting Studs

Two thumbscrews allow tool-free opening while two 2-inch mounting studs secure the door to the duct. No hinge, observation port or insulation is included, so installers must plan for separate sealing and access hardware.

Questions about this item

How does the 300-degree temperature rating hold up inside an operating duct?

The door is rated for a maximum of 300 degrees F, so it remains structurally sound in high-temperature exhaust or supply lines that reach that level.

What does the 22-gauge steel thickness mean for durability and sealing?

At 22 gauge the steel is rigid enough to resist warping under pressure while the two thumbscrew latches compress the gasket for a tight seal.

Will the 12-by-8-inch door with 2-inch studs fit my 13-inch round duct?

Yes — the frame is designed for nominal 12, 13 and 14-inch diameters; the 2-inch mounting studs bridge the curvature and the rectangular opening matches the listed door dimensions.
