Pro-source MB703672 Back Strip Brush 5/16 in 72 in Oal

Product Description

The PRO-SOURCE MB703672 is a strip brush with a stainless steel back strip and nylon bristles, designed for surface finishing, sealing, guiding, and debris-exclusion applications across industrial and trade settings. The back strip measures 5/16 inches in width, and the nylon bristles extend 6 inches in length for deep-reach coverage. At 72 inches overall length, this brush suits continuous-run or large-format installations where short brushes would require splicing. Nylon bristle construction offers resistance to moisture and moderate chemical exposure while maintaining consistent flex characteristics across a range of temperatures. Weighing 3.04 pounds, the assembly is robust enough for permanent mounting applications.

This strip brush is applicable in door seals, conveyor edge guides, machine guards, dust and air curtains, and panel or cabinet brush seals. It is well suited for use in manufacturing facilities, HVAC equipment enclosures, and industrial equipment where a flexible, continuous brush seal is required along a linear run. The 72-inch length allows a single piece to span standard door and panel openings without joints. Installation is typically performed by millwrights, maintenance technicians, or HVAC sheet metal workers depending on the application context.

Installation Notes

Strip brushes of this type are typically mounted by securing the stainless steel back strip into a matching retainer channel using mechanical fasteners or adhesive depending on the substrate. Power down or de-energize any associated equipment before fitting the brush near moving parts or electrical enclosures. Use appropriate metal-cutting tools if field-trimming the brush length, and wear cut-resistant gloves when handling the stainless steel back strip edges. Verify that the mounting channel width matches the 5/16-inch back strip before installation.
