Unfinished 1 1/14in. Left Return Stair Nose - 13in. 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 nosing (also commonly known as the landing tread) is typically used where the ascension of the stairs stops and the beginning of the next floors floor starts. It is designed to be flush with the flooring to create a seamless transition between the stairs and next level.
