sliding door handle for NAMI-302187 door

Thanks for posting. You can replace this handle set with the 82-086. Note that you might want to make sure the mortise lock in the door isn't broken, because that could be the cause of the handle set not locking. To find out, remove the handle set and try manually flipping the lock with a slotted screwdriver. If it doesn't budge, you know it's the culprit. See the 82-218 for a replacement.
