Anyone have any idea how picture frames concealing wall safes are hinged? Clearly you can't use a normal hinge as it would be obvious to a potential burglar, and I'm not sure if a conventional frame could host the kind of deep hole many cabinet overlay hinges require for cabinet doors - and I'm not sure if one of these would give a sufficient 'throw' anyway. I actually don't need the picture frame for a safe, but rather as a door to conceal a custom-made medicine cabinet I'm putting in to our secondary bathroom during a remodel. Initially I was going to eliminate the medicine cabinet anyway and simply hang a picture in the center of the wall - then I thought 'why not get the best of both worlds and have the shelving behind the picture?' As I see it the hinge will need to have around a 1" overlay so I can center the frame and have it open without the frame edge hitting the wall.\n\nAny suggestions?
