The WOOSTER BRUSH RR308-4 1/2 is a 2-pack of 4.5-inch Jumbo Koter Pro Foam Roller Covers designed for professional painting applications. Each cover features a high-capacity, density foam construction bonded to a 3/4-inch core, delivering excellent coverage and a lint-free finish. These covers are built for use with varnishes, enamels, and all paint types, making them a practical choice for finishing work where surface quality matters. Painting contractors and finishing tradespeople will find these covers suited to both interior and light commercial projects.
These roller covers are designed for use exclusively with Jumbo Koter cage frames. They are well suited for flat and semi-gloss finish work on doors, trim, cabinets, and other smooth surfaces where a foam applicator is preferred over woven fabric. The 4.5-inch width makes them effective for smaller surface areas and detail work that a standard 9-inch roller would not handle efficiently. Compatible cage frame references include True Value 419-671 and True Value 420-505.
Designed for use only with Jumbo Koter cage frames, including True Value 419-671 and True Value 420-505. Not intended for use with standard full-size roller frames.
Install the foam cover onto a compatible Jumbo Koter cage frame before loading with paint or coating. Ensure the frame is clean and dry before attaching the cover to avoid contamination of the finish coat. After use, remove and discard or clean the cover promptly, as dried paint or varnish will compromise foam integrity. Foam covers are not suitable for rough or heavily textured surfaces.
