How is the height adjustable? Does it have an adjustable rise for each step?

Hello, The 7-step steel stringer (13907) is designed for a 60" deck height (7-1/2" per step). You can slope the stringer 1/4" per step (1-3/4" forward or backward). You can send us the height of your deck to info@pylex.com. We will guide you to the right product. Thanks
