The PRO-SOURCE MB406036 is a back strip brush designed for cleaning, deburring, and surface finishing in industrial and trade applications. The brush features a stainless steel back strip that secures brass bristles measuring 1 inch in bristle length. The overall length of the brush is 36 inches, and the back strip width is 0.5 inches. This configuration makes it well suited for reaching into channels, slots, and cavities where standard brushes cannot access. It is typically installed or used by maintenance technicians, machinists, and fabricators working in production or repair environments.
This back strip brush is used in applications that require consistent bristle contact along a straight or curved surface. The 36-inch overall length allows coverage of extended work areas in a single pass, reducing tool repositioning during surface prep or cleaning tasks. Common use cases include tube cleaning, slot deburring, weld seam preparation, and general surface maintenance in light industrial and manufacturing settings. The brass bristle material resists corrosion and is suitable for use on softer metals and surfaces where ferrous contamination must be avoided.
Designed as an OEM-style replacement or direct-use strip brush for standard 0.5 inch back strip brush holders and channel-mount applications in industrial maintenance and manufacturing environments.
Strip brushes are installed by maintenance technicians or machinists and typically seat into a channel or holder that matches the back strip width. Confirm the holder channel accepts a 0.5 inch back strip before installation. Wear appropriate hand protection when handling the bristle end, as brass bristles can cause skin abrasion. Inspect the back strip for secure seating before operating any equipment that uses the brush as a component.
