Gate and Clubhouse Locks:
The locks in the past had you align the numbers on the centerline of the lock.
On todays lock there is a black line that is NOT on the centerline of the lock.
The line is located above the centerline of the lock.
(SEE the blue arrows in the picture?)
The combination needs to be centered in this line.
Just look for the black line on the lock and it will become clear.
