Tripp Lite SmartRack 21U Low-Profile Switch-Depth Wall-Mount Half-Height Rack Enclosure

The Tripp Lite SRW21U is a low-profile wall-mount rack enclosure that lets you fit 21U of EIA-standard 19-inch equipment into spaces where a full-size rack simply will not go. It is an ideal choice for network wiring closets, branch offices, classrooms, or any location that needs organized, secure, and accessible equipment storage without giving up valuable floor space.

This cabinet arrives fully assembled and ready to hang. Heavy-gauge steel construction with a black powder-coated finish supports up to 200 pounds of gear, while locking side panels and a reversible, lockable front door help you meet PCI DSS physical security requirements. Vented panels encourage natural airflow to keep switches, patch panels, and small servers running within their recommended temperature range, and the adjustable mounting rails accept devices up to 16.5 inches deep.

If your setup changes, the enclosure adapts easily. An optional caster kit converts it from a wall mount to a rolling rack, giving you the freedom to reposition hardware during upgrades or moves. Whether you are consolidating a tangle of cables in a back office or protecting critical networking hardware in a school lab, the SRW21U provides a clean, dependable foundation.
