The handle with the lock is loose because the socket for the screw snapped. The Screw Holes are 3 15/16" apart. Do you have a Chrome or Brass set that will fit. No idea who manufactured the doors or hardware.

Hello, thanks for writing in. Take a look at our 82-030. We unfortunately don't have a brass or chrome option for your style of handle. If you also need the mortise lock and keeper, see our 82-260 and 82-249.
