Lot of two different mid century Yale surface mount security locks. These are in very good condition and made in the USA. I don't think that they were ever installed, but they do have a little minor wear and soil from years in storage. One lock measures about 3 5/8" x 2 9/16" and the other is smaller and measures about 3" 2 1/4". Both bolt caps (the part that mounts on the other side) have a 3/4" long mounting flange.
