Description
The Tripp Lite SmartRack SRW21UG is a 21U low-profile, switch-depth wall-mount rack enclosure designed to securely house 19-inch rack equipment in environments with limited floor space. Ideal for network closets, classrooms, retail locations, and branch offices, this enclosure keeps critical IT infrastructure organized, protected, and easily accessible.
Constructed from heavy-duty steel with a durable black powder-coated finish, the SRW21UG supports up to 200 lb of equipment. A locking front door with a shatter-resistant clear acrylic window allows visual monitoring of devices without opening the cabinet, helping reduce tampering and acoustic noise. Locking removable side panels and vented top, bottom, and sides promote airflow to maintain optimal operating temperatures.
The enclosure ships fully assembled for fast installation and features adjustable vertical mounting rails to accommodate equipment up to 16.5 inches deep, such as network switches and patch panels. Cable access ports on the top and bottom simplify routing, while the reversible front door can be configured to open left or right. For added flexibility, the cabinet can be wall-mounted or converted to a mobile rack with an optional caster kit.
