Please note: Papaiz made a lock that had #322 stamped into the faceplate; it is discontinued. This lockset CAN be used to replace it, however, the width of the 322 lockcase faceplate was 3/4" -- 1/16" less wide than the 323 (this one). Depending on the thickness of your storm door, you may need to file the faceplate of the 323 down to make it fit correctly. How to Replace or Change Out a Mortise Lock
