The HWM2420U26WDBK is a 20U enclosed swing-out wall-mount rack cabinet with a window front door, built for mounting 19-inch rack equipment in IT and telecom environments that need a secure enclosure plus full rear access. It suits network closets, data communication rooms and structured cabling installations where active equipment must be visible behind a closed door.

Construction is mild steel with a 14-gauge welded rear section and a 16-gauge center section and doors, finished in RAL9005 black textured powder coat. The assembly comprises the HWM rear section (24W 20U), the HWM centre section, a 20U window front door assembly and one pair of 19-inch tapped 10-32 panel rails. A heavy-duty spring-hinge mechanism with concealed hinges provides controlled swing-out access, and the cabinet body is reversible so the swing direction can be set on site.
