Siemon's adjustable-depth, 4-Post Rack provides a stable platform for mounting extended depth/size active equipment. It is ideal for use in both Telecommunications Rooms and central patching areas within Data Center environments.

In addition to providing compatibility with Siemon's standalone vertical cable managers, the 4-post rack can be used with a wide range of accessories including Zero-U panels which allow for mounting of patch panels, PDU's or cable management between bayed racks or at end of rows.

The headers, vertical rails and depth adjustment brackets all feature symmetrical designs to eliminate orientation errors during assembly. They also work in conjunction to self-square the rack during assembly saving valuable installation time. The result is a rack that can be field assembled in less than 20 minutes.

  • Field Adjustable Depth - Rack depth can be field adjusted in 25mm (1in) increments to accommodate a range of equipment depths
  • Stamped U Space Indications - Provide ready visual indication of proper panel alignment
  • Slotted Mounting Holes ­ Provide a flexible securing point for ladder or wire basket trays mounted perpendicular or parallel to rack
  • In-Facing Headers and Footers - Maximize floor space while maintaining full load capabilities
