Replacement handle
We don't sell your exact handle set, but believe it or not you can use our 82-030 as a replacement. I know it looks different, but it has the same 3-15/16" hole spacing and its thumb lever is fully compatible with your existing mortise.
Look it over and please let me know if you had any questions.
I see in your purchase history that you bought our 82-080. However, the handle set we suggest to replace the above product is our 82-030. I don't think the 82-080 would work regardless of what adaptations you make to it, unfortunately.
I recommend returning that for a refund. You can see our return policy here.
Not a problem! Please let me know how it works, or if you had any follow-up questions. I'm more than happy to assist in any way that I can.
Awesome, glad to hear it! Please let me know if we can be of any further assistance. I'm always here to help.
