These shelves are junk. I ordered two, and when they came in the screws that go in the bottom to level it screwed in sideways, making this shelf unable to stand without wobbling, and several of the tabs that hold the glass in place were not level or even in the right spot so no glass shelf could sit in that space. When i asked for replacement parts, they sent me two new shelves and both had almost the same defects. the bottom screws didn't fit AT ALL this time, and the part you screw into the bar completely came out. They are not solid, the pieces bend easily. DO NOT BUY.

looks great but glass shelving on some tiers don't fit properly. Unit is a little shaky but you must attach to the wall which eliminates that problem
