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 rollers roll smoother and cover better than other mini-rollers. Specially designed to be used with the Jumbo-Koter 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. Shed-resistant white mohair is blended with nonmatting polyester fabric for a virtually line-free finish with all paints, enamels, urethanes, and epoxies. 3/4" thick professional phenolic core. The 4-1/2" length has a closed end for painting corners.
