Sliding glass door handle with lock.

Thanks for posting. This thumb lever looks like the 82-240. Note that if the lever broke, it is possibly due to the mortise lock in the door having malfunctioned. To test this, remove the handle set from the door and try manually 'throwing' the lock with a slotted screwdriver. If it doesn't budge, then you know the mortise lock has to be replaced as well. See our 82-238. For an all-new keyed handle set, see the 82-081. Let me know if you have any questions.
