Retrofit stair tread installation.
These treads are red oak with moulding trim already attached.
Retrofit stair tread kits retrofit treads are used for stair remodels when you need to remove carpet and add a hardwood tread without having to reframe everything.
The bullnose has a solid 1 to 2 wide stave to give the tread the appearance of conventional tread construction rather than an added piece.
