    45U 4-Post Adjustable Rack

    For an adjustable 4-point solution ideal for data centers and wiring closets, go with the 4-Post Adjustable Rack. Its usable depth can adjust from 26” to 38” so you’re not left with a fixed depth. To adjust the depth, simply move each bracket to your desired depth and secure the hardware in place. If you need a larger solution, gang multiple 4-Post Adjustable Racks together by using the ganging holes found on each side. You can even gang both the 24U and 45U size racks together because the holes align. For installations that require connections be made above the rack, such as trunk cabling or ladder racks, simply go through the completely open frame at the top. The 4-Post Adjustable Rack features eight ¼-20 x 0.5” grounding studs on the inside of the four rails that allow you to ground your equipment directly to those studs. Also included with the rack are serrated tooth washers that, when tightened, dig in and remove paint from the rack, establishing electrical continuity throughout the rack. With its strength, durability, and adjustability the 4-Post Adjustable Rack is a sure fit for your next installation.
