Patio door handle with lock

Your patio door handle set can be replaced with the 82-030. It has the same hole spacing.

If you are searching for a keyed version of the handle set, you'll need either the 82-030A or the 82-030B. To determine which of these is the best option, you'll need to confirm whether the thumb latch placement is centered or offset.

 The mortise lock, sold separately from the set, reminds me of the 82-226.
