The key element in our Jumbo-Koter program, these frames have the exclusive, easy-roll cage. Like high-quality standard frames, the roller moves freely and won't slide up the wall. Each frame accepts both 4-1/2 In. and 6-1/2 rollers. Because the system is unique, Jumbo-Koter roller covers only work with these frames. Constructed with solvent-resistant plastic cage for extra-smooth rolling action and 1/4 In. chrome-plated shank. Soft green Shergrip elastomeric handle adds comfort and has reinforced threads that are compatible to Sherlock GT extension poles.
