Risers for stairs are the vertical backing that go below every step and act as a "backing". They can either be stained to match your treads or painted white (or any other color).
Our treads are all 1x8 (3/4" thick x 7-1/4" high) and come in various lengths.
Red Oak and MDF (paintable) species are in stock. All other wood species take 2-3 weeks.
All prices are in USD.
