Tripp Lite's 45U 4-Post Open Frame Rack with Threaded Mounting Holes helps IT managers organize their equipment array and provides fast, easy access to installed IT equipment. The SR4POST1224 is a simple solution for housing IT equipment in secure environments and other areas that don’t require a lockable rack solution. This 45U rack features heavy-duty cold-rolled steel construction with a black powder-coated finish for durability. It supports stationary loads up to 1000 lb. The SR4POST1224 comes with all the hardware required for assembly and has a self-squaring design with bolt-down provisions. For high-density applications, multiple units can be bolted together side by side.

The open design of the SR4POST1224 provides unobstructed airflow and easy access to equipment and cabling. It has threaded (12-24) mounting holes for easy installation of standard 19-inch rack equipment. The SR4POST1224 supports equipment depths from 22 to 36 inches. This rack also accommodates toolless button-hole mounting for vertical PDUs and cable managers.
