Need clear statement of mounting requirements such as how much flat surface for wall brackets and square corners at bottom. Though I was able to figure out how to fit it to a fiberglass shower enclosure with rounded bottom corners and a bump out on each side that added extra space between shower wall and stud (yes I was able to substitute longer more substantial screws to reach the studs for mounting). Some parts provided were different than instructions indicated (4 smaller screws instead of 2 of smallest size and 2 of middle size, and cover plate for wall brackets). Would have preferred some kind of actual door stop opposite the hinge end to prevent over swinging the door *closed*. Also no instructions about firmly holding down threshold other than one screw at the hinge end (I ended up using clear JB weld a few spots out from hinge and also at far end and then caulk on both sides).
