Pro-source MB402872 Back Strip Brush 72 Inch Nylon

Product Description

The PRO-SOURCE MB402872 is a back strip brush designed for sweeping, sealing, and guiding applications across a range of industrial and commercial settings. The brush features a stainless steel back strip that provides corrosion resistance and structural rigidity along its 72-inch overall length. Nylon bristles extend 4 inches from the back strip, delivering flexible contact across irregular surfaces. The 0.5-inch back strip width keeps the mounting profile compact. This style of strip brush is typically installed by maintenance technicians, millwrights, or facility trade professionals working on door seals, conveyor guides, machine enclosures, and similar fixed or sliding contact points.

Back strip brushes of this configuration suit both light industrial and commercial applications where a continuous bristle seal or guide is needed. Common install scenarios include door bottom seals on industrial bay doors, edge guides on conveyor systems, dust and debris exclusion on enclosure panels, and draught sealing on large access doors. The 72-inch length allows full-width coverage on standard door and panel openings without splicing. The nylon bristle material performs well in dry to moderately humid environments and resists common cleaning agents.

Key Features

• Stainless steel back strip resists corrosion in damp or washdown-adjacent environments
• Nylon bristles provide flexible, low-abrasion contact on mating surfaces
• 4-inch bristle length accommodates gaps and surface irregularities
• 72-inch overall length covers full standard door or panel widths without splicing
• 0.5-inch back strip width allows low-profile mounting in tight channel or slot applications

Compatibility

Designed as a standard OEM-style back strip brush for door seals, conveyor guides, machine enclosures, and similar applications requiring a continuous flexible bristle barrier or guide strip.

Installation Notes

Back strip brushes are typically installed by maintenance or facilities trade personnel using mechanical fasteners, adhesive channels, or dedicated mounting hardware appropriate to the substrate. Ensure the mounting surface is clean and free of debris before securing the strip. For door-seal applications, verify bristle contact pressure is uniform across the full length to prevent gaps. Avoid over-compressing the bristles during mounting, as sustained compression reduces bristle recovery and shortens service life.
