Sliding door replacement handle

Hey there. If you just want to replace the thumb lever, see the 82-107. For the handle set, see the 82-086. You'll want to make sure your door's mortise lock isn't broken and the cause of the thumb latch failing. Remove the handle set and try manually throwing the mortise lock with a slotted screwdriver. If it doesn't budge, it needs to be replaced also. See if the 82-265 and 82-249 keeper match.
