12U 31-Inch Deep Server Cabinet

The StarTech RK1233BKM is a 12U wall-mount cabinet with a black aluminum frame and a depth of 31 inches. It includes a fixed 1U shelf, cage nuts, mounting screws and keys for the mesh front door and steel side panels. The unit measures 25.1 inches high, 23.6 inches wide and 33.6 inches deep.

Suits Small Server and Network Deployments

This enclosure suits offices or server rooms needing secure, ventilated storage for up to 12 rack units of networking or telecoms gear. Built-in fan mounts allow optional active cooling while mesh doors support passive airflow. Buyers needing deeper bays for large chassis or higher unit counts should consider larger floor-standing racks.

31-Inch Depth Determines Hardware Fit

The 31-inch interior depth is the critical dimension that decides which servers, switches or UPS units will fit inside. Measure your deepest device before ordering to confirm clearance. The included 1U fixed shelf adds a mounting surface for non-rackmount equipment such as modems or monitors.
