ABSTRACT:
The lock repair plate has threaded holes at the same locations as the holes in a standard mounting plate, the threaded holes being in registration with the holes in the bolt casing, which are traversed by machine screws for mounting the casing on the repair plate. The repair plate is further provided with a plurality of screw holes offset from the threaded holes and which are traversed by plate screws for mounting the repair plate on a door, the plate also being formed with an opening through which the tongue of the lock cylinder can extend, the opening being flanked by first and second pairs of apertures formed in the plate and being selectively in registration with the standard threaded bores of the cylinder which flank the tongue, one of the pair of apertures being traversed selectively by a pair of cylinder screws for securing the cylinder to the plate. A bump is formed on the outwardly facing surface of the plate as an indicator for insuring that the outwardly facing surface is not mounted facing the door.
