Open-Frame Rack for Space-Constrained Sites

The WUQ 20U open-frame rack fits retail venues, classrooms and offices where floor space is limited. Its four-post design gives clear access to ports from multiple sides so you can install and service servers, network gear and AV equipment without pulling hardware out. Adjustable depth from 23 to 40 inches accommodates a wide range of chassis lengths. Carbon-steel construction supports heavy multi-device deployments.

Carbon-Steel Frame and Mobility

The rack is built from carbon steel for strong weldability and load-bearing performance. Ground-mounted capacity reaches 500 lbs while wall-mounted capacity is rated at 150 lbs. Four included casters let you roll the enclosure into position and lock it down, saving effort during moves or reconfigurations. A top panel provides extra surface area for tools or lightweight peripherals while protecting the uppermost unit.

Sustained Load and Cable Management

With a 500 lb ground rating the frame handles fully populated 20U configurations continuously without deflection. The open structure promotes unrestricted airflow around devices during long-running workloads, reducing reliance on forced cooling. Fourteen M6 cage nuts and 145 M5 screws secure rails and patch panels for vibration-resistant mounting. A grounding wire completes the electrical safety path for permanent installations.

Questions about this item

How do I mount the 20U rack to the wall using the included M10*50 expansion screws?

Locate wall studs, drill pilot holes for the four M10*50 expansion screws, secure the rack brackets, then verify the 150 lbs wall-mounted load capacity is not exceeded.

Which hardware will need periodic checking after the rack is loaded with equipment?

Retorque the 145 M5*10 cross head screws and the 10 M6*12 cage nuts after the first week, then inspect casters and the grounding wire every six months.

At what point does the adjustable depth stop providing extra cable room?

The depth slides lock at 40 inches; beyond that the frame cannot extend, so cable management space maxes out at the 40'' setting.
