Cable grommet brush VALUE 19" Model 26.99.0420 Black — cable entry brush for 19-inch racks

VALUE 19" Model 26.99.0420 cable grommet brush in black is a brush-style cable entry designed for standard 19-inch rack cutouts. It provides a protected passage for patch cords and power leads while helping to reduce dust ingress and maintain airflow patterns inside server cabinets and network enclosures. The flexible bristles conform around varying cable diameters to minimize abrasion and allow multiple cables to pass through a single opening without sharp edges contacting insulation.

Advantages

The brush grommet offers a low-profile installation that retains a clean rack appearance while supporting cable management. Its bristle seal reduces the amount of airborne dust entering the cabinet and supports consistent front-to-back airflow. The resilient bristles protect cable jackets from chafing and help organize groups of network and power cables in a single entry point. Installation into a standard 19" cutout is straightforward and requires no special tools.

Suitable for

• Data center and server room racks where controlled airflow and dust reduction are required
• Network cabinets and patch panels with multiple cable entries
• Telecommunications and AV racks with mixed signal and power cabling
• Retrofit projects to tidy existing rack cable entries without cutting new openings

How to use

Insert the brush grommet into a compatible 19" rack cutout by aligning the frame with the opening and pressing until the unit seats securely. Pass cables through the bristles, which will flex to accommodate different diameters and bundle configurations while maintaining a brushing seal. When rearranging or adding cables, gently separate bristles as needed and feed new cables through to avoid undue stress on connectors and jackets. Periodically inspect the bristles for wear and clean accumulated dust using compressed air or a soft brush.

Usage recommendations

Use the brush grommet at all primary cable entry and exit points to support airflow management and reduce dust accumulation. Avoid forcing oversized conduits through the bristles; if larger openings are needed, select a suitably sized entry solution. Regular visual checks and light cleaning will prolong bristle life and preserve cable protection.
