broken sliding glass patio door lock handle mechanism

Hello there. The 82-107 Thumb lever will replace your old one, but I am afraid it is only available in white. If you want a new handle set altogether, see the 82-086 or 82-087, depending on the style preferred. Check to make sure your mortise lock wasn't broken and the cause of the thumb lever failing--you can do this by trying to 'throw' the lock with a slotted screwdriver. If it doesn't budge, it must be replaced. See the 82-218.
