SKU CH-3C0D-J3Q55

Square duct access door with 14 in steel panel, 22 ga thickness, fiberglass insulation and double-cam latch

  • 14 in square access door fits standard duct openings
  • 22 gauge galvanised steel construction resists corrosion
  • Double cam latch secures door under system pressure
  • Fiberglass insulation reduces thermal loss through opening
  • Tab-in hinge allows quick installation without extra hardware

14-inch square access door

This galvanised steel access door provides a 14-inch square opening for duct inspection and maintenance. The 22-gauge construction offers rigidity while remaining light enough for standard ductwork. It is designed for HVAC professionals and facility managers who need reliable entry points in rectangular duct systems.

Double-cam latch with tab-in hinge

The double-cam latch secures the panel firmly against the frame to limit air leakage. A tab-in hinge allows the door to swing open without removing fasteners, speeding up filter changes or damper checks. Fiberglass insulation on the panel face reduces thermal transfer through the opening.

Fits 14-inch square duct openings

The door covers a 14 by 14 inch cut-out, giving ample room for hand tools and visual inspection. It is not fire-rated and carries no maximum temperature certification, so it is unsuitable for high-heat exhaust or rated shaft applications. Builders needing larger access areas or fire-rated assemblies must specify a different model.

Questions about this item

How often will the fiberglass insulation behind the 14 in square steel panel need replacing?

The fiberglass insulation is built into the door assembly and is not designed as a user-replaceable component; it should last the life of the duct system under normal conditions.

What is the first limitation you hit when this access door stays in place on a pressurized duct?

The double-cam latch on the 22 ga galvanized steel frame provides the primary seal; sustained pressure beyond the latch rating will cause leakage before the hinge or panel deforms.

Does the 14 in square door radiate noticeable heat or noise when the HVAC runs continuously?

The 1 3/4 in thick insulated steel panel dampens sound and limits surface temperature rise, so radiated heat and noise remain minimal during continuous operation.
