Hi. First time poster. Hope this is the right area. I have an 18' above ground pool and just assembled one of those 3x5 free standing decks (aluminum). Actually turned out pretty good. Sturdier than I thought. Anyway, the last step is attaching to the side of the pool. The directions say to use 2 bolts/hex right into the side of the pool. Well not the side of the pool but rather the aluminum 'shell' that goes around the top of the pool (where you'd rest your hands if you were standing in the pool). Not sure I really want to drill holes in that shell. Do you guys know of any other way to secure/attach this type of deck to an above ground pool? Are there clamps or something? Thx
