Brush strip for base plate SCHROFF 27230079 – dust seal for chassis/base plate

Brush strip SCHROFF 27230079 is a removable dust-sealing accessory designed for installation on base plates and chassis in industrial enclosures. The flexible brush profile fits into mounting slots or along edges to form a continuous barrier that reduces the ingress of dust and small particles while allowing cables and connectors to pass through without being pinched. The design helps limit cable movement and rattling inside the enclosure, contributing to quieter and more reliable cabinet operation.

Advantages

The brush strip provides a simple, tool-free or low-effort method to add a dust seal to base plates and chassis. Its bristles conform to irregular surfaces and create a continuous contact line that prevents particulate entry while preserving access for wiring. Installation is reversible and does not require modification of the chassis, making it suitable for retrofit and maintenance tasks. The product's material selection balances flexibility and wear resistance for sustained performance in industrial settings.

Suitable for (tasks / use cases)

• Sealing cable entry points on base plates and chassis
• Reducing dust and debris ingress in server racks and industrial enclosures
• Minimizing cable movement and rattling in vibration-prone environments
• Retrofit sealing for maintenance or temporary installations

Key specifications

• Type: Brush-style dust seal for base plate / chassis edges
• Compatibility: Designed for insertion into mounting slots or along plate edges
• Material characteristics: Flexible bristles with a supportive carrier strip for secure placement
• Function: Allows cable passage while limiting particle ingress and reducing vibration noise
• Mounting: Removable, non-permanent attachment suitable for retrofit

How to use

Measure the length of the base plate edge or slot where the brush strip will be installed and cut the strip to the required length using suitable cutting tools. Insert the carrier strip into the mounting slot or align it along the edge of the chassis and press it into place so that the bristles form a continuous seal against mating surfaces. Route cables through the brush bristles as needed; the bristles will flex to accommodate different cable diameters while maintaining a particulate barrier. For removal, gently pull the carrier strip out of the slot or pry it free from the edge, taking care not to damage the chassis finish.

Usage recommendations

For optimal performance, keep the brush bristles free of accumulated dust and debris by periodically vacuuming or gently wiping them. Avoid exposure to aggressive chemicals or excessive heat that could degrade the bristle material. When installing on vibration-prone equipment, verify that the carrier strip is fully seated to prevent loosening, and inspect periodically as part of routine maintenance.
