Wooster Brush 4175-2-1/2 Flat Sash Brush 2.5 in

Product Description

The WOOSTER BRUSH 4175-2-1/2 is a 2.5-inch flat sash brush designed for precise paint and coating application on trim, sash, and detail work. The bristle fill is a firm nylon and polyester blend — marketed under the Ultra/Pro Mink Firm formulation — which delivers consistent pressure and controlled release across a wide range of coating types. The treated maple wood handle provides balance and grip during extended use. A round, rust-resistant steel ferrule locks the fill in place and resists corrosion from water-based and solvent-based products alike.

This brush suits residential and light commercial painting and finishing work. The flat sash profile is well suited for cutting in around windows, doors, and trim lines where edge control matters. The firm bristle formulation handles thicker coatings without losing shape mid-stroke. Painters, finish carpenters, and general contractors commonly reach for this brush on interior and exterior detail work. It is sold individually (unit of measure: EA) and is available in package quantities of 6.
