Evidently a spring was broken in our old handle, because it would drop down and not lock, unless it was pulled up. After a lot of research, I decided this was the correct Door Lock. For the most part, the parts fit. The face plate holes did not align with the holes in the door. I had to carefully drill holes to fit the plates on each side of the storm door. There was barely enough room to drill a hole. Also, the plates were squared off, mine had 3 round points on the ends. The new strike plate holes did hot align with the door frame holes, so I had to replace the old strike plate. The new door lock works well, however, you can see where tho old faseplates were.
