Request a QuoteWhat Is a Rack Brush Panel?
A rack brush panel places one or more brush strips across a cable opening. It lets cables pass while reducing open gaps, dust entry, and unwanted airflow.
Rack Brush Panel Configurations
1U and 2U describe panel height. Open and closed describe the frame. Single and opposing describe brush layout.
2U rack brush panels
- More opening height for larger cable bundles.
Single and opposing brush strips
- Single strip: brush entry from one side.
- Opposing strips: brush contact from both sides.

- Data centers and colocation facilities: cable entry across large rack deployments.
- Network and telecom infrastructure: structured copper, fiber, power, and control-cable routing.
- Data storage and high-density computing: cable entry for storage, cloud, GPU, and dense equipment racks.
- OEM server and equipment cabinets: drawing-based panels for non-standard enclosure openings.

FAQ
What is the difference between a 1U and 2U brush panel?
A 1U panel uses one rack unit. A 2U panel provides more opening height.
What is the difference between open and closed frames?
Closed-frame panels have an enclosed frame around the opening. Open-frame panels use an open-backed frame for direct cable pass-through.
Can the panel be customized?
Yes. Panel size, opening, hole pattern, brush layout, and material are made from the approved drawing or sample.
