Sorry to hear you're having trouble with our hardware. Let's address the thumb lever first, which is the easier of the two problems. The manufacturer changed the design of their handle many years ago. To keep it brief, the older style was pretty wide while the newer style, the 82-080, is a lot skinnier. The thumb lever we sell, 82-240, is designed to fit on the skinny version. It seems to always have a lot of trouble sitting in the older, wider one. The only solution to that unfortunately is to replace the entire handle set with the newer version. I know that's more than what you wanted to do but I don't think the older style thumb lever is around anymore. I apologize for the inconvenience. Concerning the mortise, I have heard this issue a few times in the past. The 82-238 is designed to work with the 89-030, which is 1/2" thick. Is yours the same size? Looking through some old threads, another possibility could be your jamb bowed out. This could have happened if the installers made the screws too tight without shimming behind the frame. You can try using a few washers to build up the keeper. Even if your frame isn't bowed that should fix the issue anyway. |
