Was at my neighbors, when my wife notice one of the kitchen drawers was
sagging. The right bracket was broken in the back where they had the two
pieces held together with some kind of plastic clip and when that broke the
neighbor used duck tape on the thing. Here is what I did to fix the problem.
I shimmed the space between the bracket and glued and screwed the shimmed to
the side panel of the cabinet. Fit the two pieces of the rail of the bracket
together and screwed the rail toward the back in one of the holes in the
bracket to the shim. That solved the problem of the sagging drawer.
