Stair Risers are installed under the stair treads and can be stained or painted (for paint-grade risers, Poplar is best). Our premium Stair risers are 3/4″ thick, 7-1/4″ high, and available in 36″, 42″, 48″, 54″, 60″, and 72″ lengths. Special order sizes are available by request. Risers are constructed either edge-glued or solid width. Surface is sanded with 120-grit paper.
