What gentle of door lock is this? I have a door lock that has 2 door handle, one larger...
I have a door lock that has 2 door handle, one larger one and under it a smaller one, the deadbolt controls 2 separate little things coming off the door contained by addition to the lock where the push button is used, those little things do serve as little locks but dont have anything needed to control them.
So to recap, the lock/handle that is controlled by the knob controls itself along with 2 other smaller things coming off the door. One on top something like 2 feet and the other 2 feet to the bottom.
Answers: it sounds close to a dead lock, normally used on plastic doors to prevent the top and bottom human being forced open.
Sounds like a Baldwin lockset. lf its an expensive home it most likley is Go to RenovatorsSupply.com for photos
