상품 소개

The insulated duct access door mounts into a prepared rectangular opening and provides a rigid, reusable closure for internal inspection. A double-wall metal panel surrounds a non-shedding insulation core, while a continuous closed-cell gasket seals against the frame. Cam latches apply even compression and a piano hinge retains the door in overhead or vertical service positions. The frame edge is hemmed or flanged into the duct wall and sealed externally so cleaning liquids and air do not bypass the opening.

주요 기능

Double-wall construction limits thermal bridging through insulated supply and return ductwork.

Adjustable cam latches apply repeatable gasket compression after each inspection cycle.

A continuous closed-cell perimeter seal avoids open corners around the access opening.

Hinged and lift-off formats suit overhead, side-wall and restricted-service locations.

응용 프로그램 솔루션

An access opening must be large enough for the intended task yet close with the same thermal and leakage integrity as the surrounding duct wall.

A cut sheet-metal cover distorts after repeated removal.A reinforced double-wall door and fixed frame preserve alignment through service cycles.

Warm humid air condenses on a single-skin access panel.Enclosed insulation reduces the temperature difference across the closure.

Uneven screw tightening leaves gaps along the gasket.Multiple cam latches distribute compression around the full perimeter.

Loose insulation fibers are exposed at the door edge.Metal skins and hemmed frame edges completely enclose the insulation core.
