I have a few suggestions. If it's just the lever latch that you need, see our 82-250. Could that lever match up to yours? If not, you could possibly adapt the 82-033 patio door handle set.
Another possibility is that the inside mortise latch could be worn. Unfortunately, your type is no longer available. If that is the case you will need to use a surface mounted locking handle set like our 82-005. You will need to drill new holes to attach it to your door. What do you think? |

We actually do not manufacture doors, so it's definitely not ours. I believe it could have been made by either Challenger Inc. Crossly Corporation, Security Aluminum Company, or Northrop Architectural Systems. I'm afraid I cannot narrow it down further. These are pretty old and no longer made. As such, information is limited. To make things easier, you may want to consider a surface-mounted handle set. These just screw right on the face of the door. You may need to drill new holes.
