The PRO-SOURCE MB404036 is a back strip brush designed for industrial cleaning, deburring, and surface preparation applications. The brush measures 36 inches in overall length with a back strip width of 0.5 inches and stainless steel bristles that extend 1 inch from the backing. Stainless steel construction throughout the bristle material makes this brush well-suited for environments where corrosion resistance is required or where contact with water, chemicals, or oxidizing materials is expected. Maintenance technicians, fabricators, and industrial service professionals typically work with this style of strip brush for edge sealing, part cleaning, and conveyor or machine guarding applications.
The MB404036 fits into a wide range of industrial and commercial service settings. Back strip brushes of this profile are commonly installed along door frames, machine openings, conveyor systems, and equipment panels to provide a flexible seal or a consistent surface-contact cleaning action. The 36-inch length allows for single-run coverage across standard-width openings or equipment spans without splicing. The stainless steel bristle material holds up in wet or chemically active environments where nylon or carbon steel would degrade faster.
Designed as an OEM-style replacement or direct-install back strip brush for industrial equipment, conveyor systems, door seals, and machine guarding applications that accept a 0.5 inch back strip profile.
Back strip brushes are typically installed by maintenance technicians or industrial service professionals using standard hand tools. De-energize or lock out any equipment before mounting the brush along moving machine components or conveyor lines. Secure the back strip into the channel or holder per the equipment manufacturer specifications, ensuring the bristle face maintains even contact across the target surface. Avoid overbending the bristle pack during installation, as permanent set in stainless steel bristles can reduce sealing or cleaning effectiveness.
