Premium Quality Knotty Alder Replacement Wood Stair Tread.
Our Knotty Alder replacement wood stair treads may range in color from a light sapwood to a light brown heartwood with reddish or peach tones. Knotty Alder is similar in character to Pine, and has solid, open knots that vary in size, shape, and color. Knotty Alder often has small and large split knots and open knots that may go completely through the wood.
Replacement stair treads, also know as retro fit stair treads, are designed to fit over your existing stair case, usually replacing carpet. Our replacement Knotty Alder wood stair treads are 3/4" thick, with a 1-1/16" thick bullnose. The bullnose is made by gluing a thin board to the bottom front of the 3/4" thick tread and then rounding the front of the entire 1-1/16" section. The bullnose is 1-1/16" thick and 1-1/4" deep. The wood tread is constructed by edge gluing boards together side by side. The number of boards is usually three or four, but can range from two to five.
All of our stair treads are made from top quality hardwoods. Our wood stair treads are not engineered and do not have a veneer. Your replacement Knotty Alder wood stair tread will be manufactured slowly and carefully. The result is a premium quality hardwood stair tread, adding beauty to any home. All replacement Knotty Alder wood stair treads are custom made and will ship within two weeks. If you don't see your desired stair tread size listed below, request a wood stair tread quote.
We can produce almost any thickness, width and length.
If you want a bullnose on the side of the stair tread, order a return. A return is a separate piece with a bullnose attached to the side of the tread. Returns should be ordered from the perspective of walking up the stairs.
The ordered dimensions always reflect the overall dimensions, including the bullnose and any returns.
Note: A return does not affect the overall length of the tread. Our returns are 1-1/4" wide. If you are measuring throat size, add 1-1/4" for each side that has a return.
The treads listed below are 3/4" thick with a 1-1/16" bullnose.
