The HWM2420U20BK is a 20U enclosed swing-out wall-mount rack cabinet with a vented front door, built for IT, telecom and structured cabling installations that need a secure enclosure plus full rear access.

The cabinet body swings out on a heavy-duty spring-hinge mechanism for front and full rear access during installation and servicing, and the body is reversible so the swing direction can be changed on-site.

Mounting (usable) space is 35.00 in (889 mm) high — 20U — by 19.00 in (483 mm) wide by 22.85 in (580 mm) deep, that usable depth being the maximum equipment depth that still allows the body section to swing out unimpeded.
