I have a broken sliding door lock for a sliding door approx 20 years old. I do not see something the same size above. Can you tell me if you would have a replacement part. Thx. The door does not have a MFR name or I would have included that.

Hi Jim; I am thinking this should be model number #04535 recessed faceplate lock. The screw holes appear to be 4-3/4" center to center

There are two other Prime-Line locks that look virtually the same but they are 4-3/4" long from top to bottom so overall they look shorter than yours

Would need to see pictures of the lock taken out and with some dimensions so we can make absolutely sure.
