Brush cable gland RAPS-1 PULSAR 1U for RACK cabinets — cable pass-through module

RAPS-1 PULSAR 1U brush cable gland for RACK cabinets provides a compact, professional cable pass-through solution that keeps cabinet panels continuous while allowing multiple cables to be routed through a single 1U opening. The module uses a dense brush interface to reduce dust ingress and to help preserve electromagnetic shielding by minimizing open gaps in equipment enclosures. Designed for standard 19" RACK frames, this cable pass-through module supports tidy cable management in server rooms, network closets, and telecommunications cabinets.

Advantages

The brush cable gland combines a low-profile 1U form factor with flexible brush filaments that accommodate cables of varying diameters without the need for separate grommets. Installation preserves the integrity of cabinet panels and helps maintain airflow patterns by filling unused gaps. The brush interface reduces dust and debris entry and contributes to improved EMI behavior compared with fully open cutouts. The module is compatible with typical RACK mounting, enabling quick replacement or retrofitting in populated cabinets.

Suitable for

• Server racks and data center cabinets
• Network cabinets and patch panels
• Telecommunications and AV equipment enclosures
• Retrofit and new installations requiring organized cable entry

Key specifications

• Height: 1U form factor suitable for 19" rack openings
• Brush-type seal for dust reduction and partial EMI shielding
• Accommodates multiple cables of varying diameters through flexible filaments
• Low-profile design to preserve rack space and airflow
• Material: durable panel and brush filament construction for repeated use

How to use

Mount the module into a standard 1U rack opening using the cabinet’s mounting points or screws. Route cables through the brush filaments, which will conform around cable bundles to maintain a tidy pass-through and reduce open gaps. For best results, avoid forcing excessively large bundles through the brush; instead, distribute cables across the module to keep pressure on the filaments moderate. The unit can be removed and reinstalled during maintenance or re-cabling operations without special tools in most rack configurations.

Usage recommendations

Use the brush cable gland to improve cable organization and reduce dust ingress while preserving cabinet panel continuity. For optimal performance, space cable bundles evenly across the brush, avoid sharp bends immediately adjacent to the filaments, and inspect the brush periodically for accumulated debris. When electromagnetic compatibility is a concern, combine the module with proper rack grounding and shielding practices.
