Unfinished Reversible Riser - 48in. is a stair part that has been left unfinished so you can give it a color and finish that suits the style of your staircase. Bring it home and then stain and finish it to your preference.
The stair risers are the vertical part of the staircase that your toes typically kick when you ascend to the next floor level. The standard box risers properly fit into staircases that have walls or obstructions on both sides of the tread.
