Access Doors—
Standard, Hinged/Latched, and Pressure-Relief for Duct Systems

McGill AirFlow's access doors provide a convenient way to reach or inspect fire dampers and other equipment located inside a duct system. To meet the needs of a variety of applications, we offer three types of access doors: standard bolted, hinged/latched, and pressure-relief doors.

Standard bolted access doors are available in galvanized steel, stainless steel (type 304 or 316), pvc-coated steel, black iron (16 gauge) and aluminum. We can supply them loose or manifolded to the duct. Hinged/latched and pressure-relief access doors are also available in galvanized steel, stainless steel (type 304 or 316), pvc-coated steel, black iron (16 gauge), and aluminum. They can be provided loose or manifolded to the duct, or attached to fitting bodies.

Specifications for access doors can be found in McGill AirFlow's publication Recommended Specifications for Commercial and Industrial Duct Systems.
