2-Inch Angle Sash Brush for All Coatings

The Wooster Ultra/Pro Firm 4174-2 is a 2-inch angle sash brush built with a purple synthetic blend of polyester and nylon filaments. Its firm bristle stiffness and 9/16-inch thickness hold a generous paint load for controlled cutting-in on trim, corners and edges. The wood sash handle balances comfortably for extended detail work on interior or exterior projects.

Replaces Worn Sash Tools When Cutting-In Fails

Swap this brush in when an old sash brush loses its flagged tips, splays under pressure or leaves ridges in acrylic and water-based coatings. The firm synthetic blend keeps its shape on smooth and medium surfaces such as drywall, wood, metal and concrete. The upgrade is worth it when you need a clean cut line without the brush pushing paint onto adjacent glass or moulding.

Simple Hand Tool With No Mechanical Fuss

No assembly or adjustment is required; dip the filaments, tap excess and cut in. The most common issue is dried paint hardening at the ferrule if the brush is not cleaned promptly after use with water-based products. Thorough rinsing and reshaping the tip while wet preserves the firm stiffness and precise angle for the next job.

Questions about this item

What handle length and ferrule width does the 2 in. angle sash brush have for fitting a standard brush holder?

The brush has a 2 11/16 in. bristle length and a 9/16 in. bristle thickness, with a wood sash handle designed for trim and cutting-in work.

How do I prep the synthetic polyester/nylon filaments before first use, and what step do painters often skip?

Rinse the purple filaments in warm water to remove loose fibres, then spin out excess moisture; skipping this rinse can leave stray bristles in the first coat.

When should the firm polyester/nylon blend be replaced if used daily on smooth drywall and wood with acrylic paint?

Replace the brush when the 2 in. tip loses its sharp angle or the 9/16 in. thickness splays, typically after several large interior jobs with proper cleaning.
