This frame-less wall cabinet is melamine with a thin press-board backing, and it has no hanging rail. The press-board backing is set back from the rear of the cabinet about 5/8". The cabinet seems pretty heavy for it's size.
It was a shop project about 20 years ago and just takes up workbench or countertop space; not sure why anyone got an "A" on it without a way to mount it! I'm sure that if I just screw through the press-board to mount it, it will simply break and tear through the press-board, even if I fill the space behind the press-board.
It will be a stand alone, with no cabinet or wall next to it, so I can't screw through the sides.
I'm thinking that if I glue and screw a filler behind the press-board, it might hold, but it still won't be attached to the cabinet except for the thin backboard, and I just don't want to have to worry about it once it's hung and filled with misc. hardware.
Any great ideas would be welcome!
