Our retrofit stair treads are milled with new state of the art equipment. We can make the retrofit stair treads with a left or right hand return. Or we can make them with a double end return to any length. Knotty alder retrofit stair treads are available in standard sizes or can be custom made to your specifications. Retrofit stair treads are also available in almost any other hardwood species.
All sizes are overall, including the return(s). For example, a single return 36" tread will have a 34-3/4" throat size.

Knotty Alder wood is light tan or light brown with a yellow or reddish ting. The fine even texture and moderate density of alder wood makes it easy to work with. Alder sands and polishes easily, stains readily, and seldom splits. We use only the higher quality grades of knotty alder lumber for our products.
