Vintage Yale Nickel Thumb Turn Mortise Locks – Many Available

These mortise locks work with a thumb turn to throw the deadbolt rather than a skeleton key.  These locks have a doorknob spindle hole that is just a hair smaller than most threaded spindles. Some still work with the locks but you would be better pairing these locks with door hardware that uses a straight spindle with set screws.

Clean with strong return springs. Chrome plating on the faceplate has some dings and scratches but that is expected for old hardware.  Reversible for right or left hand doors.  Just open the lock and flip the strike over.
