Pro-source MB404472 Back Strip Brush 72 in Stainless Steel

Product Description

The PRO-SOURCE MB404472 is a stainless steel back strip brush designed for sealing, wiping, guiding, and protecting applications in industrial and commercial settings. The brush measures 72 inches in overall length with a 0.5-inch back strip width and 3-inch stainless steel bristles. The stainless steel bristle construction resists corrosion and holds up in wet, chemical, or high-debris environments. Licensed tradespeople and maintenance technicians install this type of brush in door frames, conveyor lines, machine enclosures, and similar channel-mounted applications where a flexible, durable seal or wipe is required.

This back strip brush suits commercial door thresholds, industrial enclosures, conveyor guards, and equipment panels where a continuous flexible bristle barrier is needed. The 72-inch length makes it practical for full door-height or long-run machine applications. It ships as a single unit and can be cut or fitted to length depending on the installation channel. No specific brand or model compatibility is stated by the supplier for this SKU.

Installation Notes

Back strip brushes are typically installed by maintenance technicians or millwrights using standard hand tools to seat the strip into a channel or track. Ensure the mounting channel is clean and free of debris before seating the brush. The strip can be cut to length with metal snips or a hacksaw where the stainless steel back is present. Secure mounting hardware per the equipment manufacturer's specifications.
