Wooster Brush RR941-4 1/2 Roller Cover 4 in 3/8 Nap 2 Pack

Product Description

The WOOSTER BRUSH RR941-4 1/2 is a Jumbo-Koter Super/Fab roller cover designed for applying flat, eggshell, and satin paints on smaller or detail surfaces. Each cover measures 4 inches in width with a 3/8 inch nap depth, making it well-suited for smooth to slightly textured surfaces. The fabric construction features Hydro Flow Technology, which regulates paint release for a more consistent, controlled application. The shed-resistant fabric minimizes lint and fiber dropout in the finish coat. This product is sold as a 2-pack, providing an immediate backup cover on the job. Painters, maintenance professionals, and finishing contractors are the primary users of this cover.

The RR941-4 1/2 is intended for use on smooth and lightly textured interior surfaces such as trim, doors, cabinet faces, and accent walls where a standard 9-inch roller would be oversized. The 4-inch frame size fits the Jumbo-Koter mini roller system. It performs with latex-based flat, eggshell, and satin paints. The controlled nap depth and tight fabric weave deliver a smooth finish with minimal stipple on properly prepared surfaces. Suitable for both residential repaint work and light commercial interior finishing applications.

Installation Notes

Install the cover onto a compatible Jumbo-Koter mini roller frame before loading with paint.

Clean covers promptly after use according to the paint manufacturer's solvent or water-cleanup instructions. Store unused covers in their original packaging to protect the nap.
