The APC® NetShelter® WX 13U Enclosure is specifically designed for networking professionals to securely store and wire 19-inch EIA compatible equipment such as hubs, routers, concentrators and patch panels. It is suited for small hub and LAN applications within wiring closets and computer rooms with floor space constraints. You can mount the enclosure directly to building walls with the four key hole slots spaced 16" apart on the rear door. The eight 2" cable access holes located at the top, sides, and bottom of the rear door provide you with ample cabling provisions. The front mounting rails with threaded holes can be adjusted to allow for various mounting depths and to allow for additional clearance from the front door. This enclosure comes in a double-hinged design — providing front and rear access to the installed equipment.
