Rouleau Uni-Step Tread/Riser is a convenience for installers who wish to use a one-piece tread and riser combination instead of the traditional separate tread and riser. Uni-Step Tread/Riser is made from 1/8” vulcanized, molded rubber with a unique flexible joint at the riser. With fewer seams, the Uni-Step Tread/Riser is much easier to clean and maintain. Tread/riser depth is 19.5 inches, in lengths of 3 ft., 4 ft. and 6 ft., in 25 Uni-Color colors and can be ordered with visually-impaired abrasive strips.
