It rains a bit here in the Northwest and it doesn't take much moisture to slip on a stair and take a nasty tumble. Even walking down slick basement stairs can be a hazard! Here's a nice solution that you can install yourself. Our rubber Stair Treads are 29 1/2" wide by 9 3/4" deep and can be cut to your specification. Affix to the stair step with the adhesive tape provided on the bottom or you may tack it down or glue them in place. The 1 1/4" long lip folds over the edge of the tread for extra grip and a nice finished look. Made of natural rubber that remains flexible, even in sub-zero temperatures. Imported.
