These shelves looked great and were easy to install. BUT you cannot overlap frames- even very shallow 3/4” wide frames. They do fit in the 2.2” shelf opening overlapped but once the shelves are hung on the wall, if the frames are overlapping or 2-deep, they both fall forward and crash to the floor. The worst part is you cannot tell this will happen until you’ve already installed the shelves in the wall. Returning.
