Wooster Brush RR666-9 Roller Cover 9 Inch 3/8 Nap

Product Description

The WOOSTER BRUSH RR666-9 is a 9-inch roller cover with a 3/8-inch nap, designed for applying a wide range of coatings including flat, eggshell, satin, semi-gloss, gloss, enamels, primers, urethanes, and epoxies. The cover features an exclusive white fabric construction with a double golden pinstripe that promotes a smooth, even finish and increases paint capacity per load. The green double-thick polypropylene core is engineered to resist water, solvents, and cracking, extending the usable life of the cover across multiple coating types. Painters, finishing contractors, and maintenance professionals use this cover for interior and exterior surface work.

This roller cover is suited for residential and light commercial painting applications. It performs across smooth to slightly textured surfaces where a fine finish is required. The 3/8-inch nap depth makes it well-matched to surfaces such as drywall, plaster, wood trim, and previously painted substrates. Its compatibility with solvent-borne and water-borne coatings makes it a versatile choice when a single cover type needs to handle multiple product chemistries on the same job.
