An excellent roller for painting all small areas. It also excels at cutting-in, keeping a consistent finish texture near the trim or ceiling line. Jumbo-Koter<reg> rollers roll smoother and cover better than other mini-rollers. Specially designed to be used with the Jumbo-Koter<reg> frame model No. RR013 or RR014. Due to the unique cage, it utilizes a larger diameter with 75\% more fabric than small mini-rollers. It greatly increases capacity, but even without the extra fabric, offers much better coverage due to the professional fabric quality. Golden yellow fabric blend of 50\% lambswool and 50\% polyester for 100\% performance in flat or satin paints, stains, and sealers. Fabric is bonded to a thick 3/4 strong core. Wool provides maximum paint capacity and a smooth finish; polyester reduces matting in warm weather or when using latex paints.
