What 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. U height alone does not confirm fit: check rack width, hole pattern, opening position and clearance.

Open and closed rack brush panel configurations

1U rack brush panels

  • Closed-frame: enclosed frame around the cable opening.
  • Open-frame: open frame for direct cable pass-through.

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. A component material rating does not establish a UL 94 V-0 rating for the complete assembly.

  • 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. For already connected cables, specify an open, split or otherwise accessible frame that fits around the installed connectors.

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. The brush is not a hermetic seal; dust and airflow performance must be checked in the installed enclosure.

  • 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.
