Rick,
This is the exact lock that was installed on ours and it is NOT good!
I suggest you utilize one of the great solutions the others have come up with, or do like I did (we didn't want to put screws anywhere) and come up with your own.
Fred,
This is an interesting solve! How long has this been working for you? My concern is that this door is SO heavy, and it seems that the first roller to jump off the track during a quick stop, is the one on the curve of the door...the one closest to the wall when open...and your pin seems a bit far from "problem", if ya get my drift. A long kitty corner distance...might'nt the roller still come off, torquing the door and twisting the pin?
That is why I'm curious to know how long this has worked for you. The DH might go so far as to try THIS, lol, if it is a proven fix, like Eds! So far my suction cup idea is doing very well but does not put any downward pressure on the door.
Thanks!
Carol
