(2) Check the door
(a) Door thickness range:
(b) Lock mounting hole diameter range:
(Large holes in this range will make the installation process easier)
(c) Distance from the center of the lock mounting hole to the edge of the door (latch hole side):
If the parameter of your door does not meet the above requirements, it does not necesarrily mean it cannot be
installed. Please call us for further advise.
If your door does not have a ready-made lock mounting hole, you need to complete the additional hole-drilling
work yourself. The product box contains a cardboard template to help you position the holes correctly.
(3) Installation tools
A M4 Phillips screwdriver if mounting holes are ready.
