The covering on the riser of mine is only plywood so there is no real strength to it. You should at least look at it from the back to see what is there to hold any screws you put in. I may sound like a broken record, but if you take the wall off in the basement, use heavy-duty velcro to refasten it in place. You will be going in there again sometime.
