Description
The Tripp Lite SmartRack SRW21U is a 21U low-profile wall-mount rack enclosure designed to securely house 19-inch network equipment in space-constrained environments. Ideal for network closets, classrooms, retail locations, and back offices, this cabinet provides professional-grade organization without consuming valuable floor space.
Constructed from heavy-duty steel with a durable black powder-coated finish, the SRW21U supports equipment loads up to 200 lbs. Locking front door and side panels help protect sensitive IT equipment from tampering or unauthorized access, while vented panels on all sides promote efficient airflow to maintain proper operating temperatures.
The enclosure accommodates network switches, patch panels, and other shallow-depth equipment up to 16.5 inches deep. Adjustable vertical mounting rails, numbered rack spaces, and multiple cable access ports simplify installation and ongoing maintenance. The reversible front door allows left- or right-hand opening for flexible wall placement, and the unit ships fully assembled for fast deployment.
