Wooster Brush RR981-4 1/2 Knit Roller Cover 4.5 in 2-pack

Product Description

The WOOSTER BRUSH RR981-4 1/2 is a 4.5-inch knit roller cover designed for use with the Jumbo-Koter mini roller system. The cover measures 4.5 inches wide with a 3/8-inch nap depth and is constructed from a proprietary golden yellow knit fabric exclusive to Wooster Brush. This nap profile makes it well suited for flat, eggshell, and satin finishes as well as stains and waterproofing coatings. The closed-end design is compatible specifically with the Jumbo-Koter frame system. Sold as a 2-pack, this cover is a standard replacement or backup option for painters working in detail areas, cabinets, trim, or other tight applications that require a smaller roller.

This roller cover is intended for use in residential and light commercial painting applications where a full-sized roller is impractical. Typical uses include doors, cabinet faces, shelving, furniture, and accent walls. The 3/8-inch nap handles smooth to slightly textured surfaces. It accepts flat, eggshell, and satin latex or oil-based paints, as well as stains and waterproofing products. The golden yellow knit fabric is engineered to resist matting during application, which helps maintain consistent film thickness and reduces the need for repeated reloading.

Installation Notes

Slide the cover onto a compatible Jumbo-Koter frame before loading with coating material. Rinse new covers with water before first use with latex products to remove loose fibers. After use, clean the cover promptly according to the coating manufacturer's solvent recommendations to extend cover life.
