I have three sears storm doors. Two are model #65623650271. The third one is model #65623660271. All latches appear to be like the one in the photos sent. The latch has a patent #3955839 stamped on it. I need three (3) interior latches with the screws.

Hey, Steve. Please compare our 40-117 to your latch to confirm if this can work.
