Hello, We can't say for sure what you need without seeing the original part but your keeper looks a lot like our 89-030, which is commonly used with our 82-238 mortise lock. Your handle set resembles the 82-080 but if you just need a new thumb latch, see our 82-240. Make sure to compare our dimensions to your hardware and the hole placement in your door to confirm that these parts will work for you. Thanks for posting! |
