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 (24U and/or 45U) by using the ganging holes found on each side. 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 ź-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. Durability
The 4-Post Adjustable Rack's welded L bracket base and cold rolled steel design forms a sturdy, reliable rack. Floor mounting holes are available to secure the rack to the floor for maximum durability. We always recommend installing your heaviest equipment at the lowest points on the rack. Gangable
Ganging holes on both sides of the rack make it easy to gang and secure multiple racks together. The sides also feature cable pass through holes to allow cabling to pass from one rack to the next. Electrical Grounding
The rack features eight ź-20 x 0.5" grounding studs on the inside of the four rails. These studs allow you to ground your equipment directly to the stud or with the use of bus bars, not included. The rack also includes serrated tooth washers to allow the frame to be grounded during the assembly process. Open Top Design
The 4-Post Adjustable Rack's completely open top allows for smaller trunk cabling, and makes the rack compatible with most ladder racks and accessories. 1940-3-100-45 Includes: - Qty 4 – 45U Rails
