Network rack brush strip Renkforce RF-3429146 48.30 cm 19" Black

Brush strip Renkforce RF-3429146 is a 48.30 cm, 19"-compatible panel accessory designed to close horizontal or vertical openings in server cabinets and network racks. The black brush material provides a controlled pass-through for patch cables while limiting dust ingress and supporting airflow management inside the cabinet. The product is intended for use in professional IT closets, telecom cabinets and structured cabling installations where cable access and rack cleanliness are required.

Advantages

The brush strip reduces dust and debris entry into racks while allowing multiple cables to pass through without sharp edges or abrasion. Its 19" form factor and standard length make it compatible with typical rack units, and the flexible bristles accommodate variable cable diameters, preserving cable insulation and connectors. The black finish integrates unobtrusively with common rack equipment and contributes to improved hygiene and cable routing neatness.

Suitable for

• Filling unused horizontal or vertical openings in 19" server racks and network cabinets
• Providing a sealed pass-through for patch cords, power cords and fiber pigtails
• Reducing dust ingress and supporting cabinet airflow management
• Organizing cable entry points in data closets, comms rooms and telecom cabinets

Key specifications

• Compatibility: 19" rack-mount form factor
• Length: 48.30 cm
• Finish: black
• Mounting orientation: suitable for horizontal or vertical installation
• Material: flexible brush bristles designed to reduce abrasion on cables

How to use

Install the brush strip into an available 19" opening on the front or rear of the rack by aligning it with the rack mounting rails and securing it according to the cabinet's standard mounting method (screws or captive fasteners as applicable). Pass patch cords, power leads or fiber pigtails through the bristles where needed; the flexible bristles will conform around cables to maintain a barrier against dust while permitting cable movement. Inspect placement to ensure no excessive compression of cables or sharp contact points.

Usage recommendations

Use the brush strip in combination with proper cable management accessories (cable ties, horizontal managers, and cable trays) to maintain airflow and prevent bundle strain. Periodically check and clean the bristles to remove accumulated dust. Avoid overloading a single pass-through area with too many large-diameter cables to prevent excessive abrasion or compression.
