These are attached with a bolt on each side and they lay on the two pipes of the shelves. The problem is, the hole for the bolt is off just enough that the shelf doesn't quite touch both the front and back pipe at the same time. Makes it feel a little wobbly - not a lot but enough to notice. Plus dropping kettlebells on sheetmetal feels a little weird. If I were to do it again, I'd make something out of plywood with rubber on top. But it is made from thick sturdy steel and the prices is really good, so you can also consider getting it and putting something down on one of the pipes to close the gap if yours has this problem too.
