HWFVD3036UBK is a vented front door built for 36U, 30 in wide HWF Series wall and floor mount rack cabinets. It is sold separately from the cabinet and is intended for IT and telecom installations where the rack enclosure needs to be closed off for security while still allowing air to pass through the front of the equipment stack.

The door panel uses a 63% free-area perforation pattern, with a perforated zone measuring 20.00 in (508 mm) across by 30.2 in (768 mm) in the front view, so cooling air can reach front-facing network and server equipment without an unvented barrier. The finish is black textured paint, and the door is made of mild steel. Nominal size is listed as 63 in x 30 in x 1 in (1,600 mm x 762 mm x 25 mm), with a shipping weight of 40 lbs (18.14 kg).

The assembly ships with the hardware needed to hang and secure the door: three surface door hinges (LH) with three hinge cover plates, a swing handle key lock (FH333), an offset cam (.560), three stick-on rubber bumper feet and six #10-24 x 3/8 thread-cutting screws. Hinge components and latch hardware are shipped loose for field assembly, so the door can be set up for the required hand on site.

Within the HWF Series, HWFVD3036UBK pairs with the 36U cabinet height; solid and window door versions are offered for the same size if a different level of visibility or airflow is preferred. Per the series data, an HWF cabinet with a door installed meets PCI DSS requirements. The part carries cULus recognition under UL file E475597, is TAA-compliant, made in Canada, and is RoHS and REACH compliant.
