Once the backset is installed, slide the latch (front part of the lock) through the hole. Check it is aligned and once in the right position, you can now install the back part of the doorknob or handle. If your knob has a lock feature, you want the lock to be facing the right way. Be sure to test the doorknob/handle any locking mechanism before securing everything into place.
