Brush Cable Gland for Rack Cabinets PULSAR RAPS-U — pass-through for RACK RWA/RW/RWD

PULSAR RAPS-U is a brush cable gland designed for installation in rack cabinets and enclosures compatible with RACK RWA, RW and RWD series. The product creates a sealed pass-through point for bundles of power, data and signal cables while limiting dust ingress and minimizing undesired air exchange between cabinet compartments. The dense brush insert holds cables in place and supports neat cable management in server racks, network cabinets and electrical enclosures.

Advantages

The brush cable gland provides a flexible, reusable sealed entry without requiring individual grommets for each cable. Its dense bristles reduce dust and particulate entry and help maintain cabinet airflow balance, which supports thermal management. The unit is compatible with common rack mounting cutouts of the specified RACK series and simplifies routing of mixed cable types through a single opening.

Suitable for

• Server racks and data centre cabinets
• Network and telecom cabinets
• Electrical enclosures and control cabinets
• Areas where reduced dust ingress and controlled airflow between compartments are required

Key specifications

• Type: brush cable gland for rack cabinets
• Mounting: pass-through insert for compatible rack cutouts
• Seal: dense brush insert for cable sealing and retention
• Compatibility: designed for RACK RWA, RW and RWD series enclosures
• Application: supports mixed power, data and signal cable routing

How to use

Prepare the cabinet cutout according to the dimensions of the rack series, insert the brush gland into the opening and secure it following the cabinet manufacturer’s mounting method. Route the cable bundle through the bristles; the flexible fibers will conform around cables to provide retention and reduce airflow and dust transfer. Adjust cable positions as needed to optimize access and strain relief, and ensure the cabinet door and any blanking panels are correctly closed to preserve airflow characteristics.

Usage recommendations

For effective dust reduction and airflow control, group cables to minimize large gaps between bristles and avoid overfilling the gland. Periodically inspect the brush insert for accumulated debris and clean with compressed air or a soft brush as part of routine cabinet maintenance.
