The shallow depth of the SR45UBSD is an ideal cabinet for shallow-depth audio/video equipment, smaller equipment installs or areas with limited floor space. It houses 3000 lb of standard 19-inch rack equipment in 45U. Its front and rear pairs of vertical rails have square mounting holes that are adjustable in quarter-inch increments from 4 to 27 inches. Adjustment is quick and an easy-view depth index ensures consistent rail placement without requiring time-consuming measurements. Each rack space within the enclosure is numbered for ready reference. All components of the SR45UBSD are grounded to the enclosure frame. Front and rear threaded grounding points are provided for connection to the facility earth ground. The removable front and rear doors feature quick-release ground wires.

The top panel of the SR45UBSD is vented to help remove warm air from the enclosure and draw in cool air by convection. The top panel includes ports for cable routing, and can be quickly removed without tools. To facilitate cable access, the SR45UBSD is open-bottom.

With its locking, reversible, removable front and rear doors, and locking, removable side panels, the SR45UBSD provides ultimate equipment safety. The side panels are half size for ease of removal and reinstallation. The split rear door design allows the enclosure to be placed closer to a wall. The SR45UBSD meets all requirements toward PCI DSS compliance. To simplify deployment, the SR45UBSD comes with preinstalled casters that enable it to be easily maneuvered into the desired location, where it can be secured by adjusting the preinstalled levelers. Note: the casters are intended for minor position adjustments and are not designed for moving the enclosure over long distances.
