Hello - when it says, use with a left hand hung door. Is that looking from the outside of the house or inside looking out?
Edward Evans, Southsea
When trying to determine if you need a left or a right handed door lock, stand on the outside of the door. If the lock is on the left, you need a left handed lock. If the lock is on the right, you need a right handed lock.
