Cable entry brush ProBase CO-BT-145x70 145×70 mm brush cable gland panel insert

ProBase CO-BT-145x70 is a brush cable gland panel insert sized 145×70 mm designed to provide a tidy, rectangular opening for multiple cables while reducing dust ingress and air drafts. The brush module fits flush into a rectangular cutout in control cabinets, telecom racks or equipment panels, allowing cables to pass through a dense bristle field that maintains a neat appearance and preserves basic enclosure separation between internal and external environments.

Advantages

The brush insert offers flexible cable routing without fixed holes, enabling cables of varying diameters to be routed together without additional sealing components. Bristles conform to cable shapes to limit dust and airflow while minimizing abrasion. The low-profile frame and simple rectangular form factor simplify mounting into standard panel cutouts and support quick installation and maintenance access.

Suitable for

• Control cabinets and switchgear panels where multiple signal and power cables enter or exit
• Telecom and server racks requiring tidy cable pass-throughs
• Equipment panels in manufacturing machines and test benches
• Enclosures that need dust reduction and draft control without rigid grommets

Key specifications

• External frame dimensions: 145×70 mm (rectangular panel insert)
• Material: plastic frame with dense synthetic bristles
• Mounting type: panel cutout insert for rectangular opening
• Colour: typically black or dark finish to match enclosures
• Function: brush-style cable sealing allowing flexible cable diameters

How to use

Select an appropriate rectangular cutout in the panel matching the 145×70 mm frame dimensions and ensure the panel thickness is compatible with the insert. Push the brush module into the cutout until the frame seats flush; use any recommended retaining clips or screws if required by the panel design. Route cables through the bristle field; the bristles will conform around cables to maintain a tidy pass-through while limiting dust and drafts. For removal, carefully pull the insert out of the opening or release fasteners, then slide cables free of the bristles.

Usage recommendations

Install the brush module where grouped cable entry is required and avoid using it for sharp or heavily vibrating cables without additional protection. For environments with heavy contamination or liquid exposure, consider a purpose-built sealed gland. Periodically inspect the bristles for wear and remove accumulated debris to maintain effectiveness.
