handle set with a lock and key

Hello,

Your handle set resembles the 82-030 depending on if the 3-15/16" hole spacing matches your assembly. If so, you should be able to use either the centered 82-030A or the offset 82-030B keyed handle set depending on the position of the thumb latch on your internal handle. Take a look and let us know if you have any other questions. Thank you!
