Not sure what secures the handle in place. There are no set screws. Looking to replace the handle only on one side.
Can you help identify?
No markings or numbers anywhere.

The inside latch looks like either our 40-145 or 40-150. If you want the entire handle set, see if the 40-058 could work for you.
