Made my own for .75 a piece with simple supplies from Home Depot, a $7.50 roll of grip tape from Amazon and a laminate scoring knife. I use the hardback wood board from Home Depot which is 7.50 and can cut 18 stair strips. I used framing screws to secure them to the stairs and carpet tile adhesive strips to cover the screw holes . They are all consistently cut and adhered safely to the stairs.
