20U 4-Post Wall Mount Open Frame Rack, Side Mount, Floor-Standing w/ Casters Flat Box

The 20U Wall-Mount 4-Post Open Frame Rack is a flexible rack solution designed for mounting 19-inch servers, A/V equipment, and networking hardware in space-limited environments such as network closets, back offices, and IT rooms. Supporting both front-mount and side-mount configurations, it allows equipment to be installed parallel or perpendicular to the wall for improved accessibility and optimized airflow. Constructed from heavy-duty SPCC cold rolled steel with a durable black RAL9005 powder-coated finish, the rack supports up to 790 lbs when floor standing and 200 lbs when wall mounted. Its open-frame design promotes maximum front-to-rear airflow, helping reduce heat buildup while allowing easy access for cable management and maintenance from any side. The rack features #12-24 threaded and square mounting holes and includes one 1U vented shelf and one 2U vented shelf for additional equipment support and airflow. Shipped flat-packed with assembly hardware, it provides a durable, easy-to-deploy solution for professional IT, telecom, and AV installations.
