1U rack brush panels
- Closed-frame: enclosed frame around the cable opening.
- Open-frame: open frame for direct cable pass-through.

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 We Manufacture
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.
Custom rack and enclosure panels
- Specify size, opening, hole pattern, material, and brush layout from a drawing or sample.
Brush Fill
Dense PA6 nylon and specified flame-retardant options are available for cable entry. The final material grade and required documentation are confirmed for the approved construction.
- Dense black, straight PA6 nylon for cable entry.
- Specify filament diameter, fill density, any required UL 94 class, the component to which it applies, and the supporting material documentation required for approval.
Panel Construction
Panel bodies and brush strips are selected around the rack opening and mounting requirement.
Rigid PVC H-profile body
- Pre-drilled 1U reference construction with tufted brush fill.
Steel-shell rack panel
- Steel panel with a nylon brush strip at the cable opening.
- Specify material, hole pattern, finish, and hardware on the drawing.
Common Applications
Rack brush panels are used where cables enter equipment while the opening should remain covered around the cable bundle.
- 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
Does a 1U or 2U size guarantee that the panel will fit my rack?
No. The U size mainly describes panel height. Confirm the rack or enclosure width, rail and mounting-hole pattern, cable-opening position, hardware, and available clearance. State any required 19-inch rack standard or other mounting interface on the drawing.
What information should I send for a rack brush panel quote?
Provide the rack width, U height, overall panel size, opening dimensions and position, mounting-hole pattern, panel material and finish, cable-bundle size, single or opposing brush arrangement, required material documentation, quantity, and a drawing or sample.
Should I use a single brush strip or opposing brush strips?
The choice depends on opening height, cable-bundle size, permitted insertion force, and the coverage required around the cables. Opposing strips can cover the opening from both sides, but the remaining pass-through space must still suit the installed connectors and cable bundle.
Can a rack brush panel be installed around cables that are already connected?
It can be designed for that situation when an open, split, or otherwise accessible panel construction is specified. Provide the installed cable and connector dimensions and access limits; a closed panel should not be assumed to fit around existing connections.
Can you provide a specified flame-retardant rating?
State the required UL 94 class, which component it applies to, and the document needed for approval. Flame performance depends on the confirmed filament, carrier, and panel materials, so the complete assembly should not be described as UL 94 V-0 unless that exact construction and supporting evidence have been verified.
Does a rack brush panel guarantee dust sealing or airflow performance?
The brush can reduce the open gap around cable entry and support airflow management, but it is not a hermetic seal. Actual dust and airflow performance depends on the opening, cable fill, brush density and overlap, installation gaps, and the complete rack cooling system; validate the result in the installed enclosure.
