Pro-source MB402636 Back Strip Brush 36 in Nylon

Product Description

The PRO-SOURCE MB402636 is a back strip brush designed for cleaning, sealing, and finishing applications in trade and industrial environments. The brush features a stainless steel back strip and nylon bristles measuring 3 inches in length. The overall length is 36 inches, making it well-suited for runs that require consistent contact along channels, door frames, conveyor edges, or similar linear surfaces. The 1/2-inch back strip width provides a compact profile that fits standard mounting slots and extrusions. Plumbers, HVAC installers, millwrights, and general contractors reach for this style of brush when they need a durable, corrosion-resistant sweep or seal along a continuous edge.

This back strip brush is used in light industrial, commercial, and residential construction settings. Common applications include door bottom seals, window and panel edge seals, conveyor guiding, cable management runs, and debris deflection along equipment frames. The nylon bristle construction handles contact with moisture and mild chemicals without degrading, and the stainless steel back strip resists rust in wet or humid install environments. At 36 inches overall length, the brush can be cut to length on-site to match the specific run required.

Installation Notes

Installation is typically performed by carpenters, millwrights, or general contractors using standard hand tools. The stainless steel back strip can be cut to length with aviation snips or a metal shear — avoid scoring and snapping, which can deform the channel profile. Secure the back strip in the mounting channel before pressing or fastening it in place. Inspect bristle alignment after installation to confirm full contact with the mating surface.
