3.1
Insert the nylon plug into the holes and tap them in gently
using a hammer.
3.2
Using four screws, fix the Lockbox to the wall.
a)
Install the top two screws first by sliding the box up in the
slotted top holes to its highest position (to allow for easy
access to the bolt heads).
b)
Screw them down to within one turn of being tight, but
do not fully tighten at this stage.
3.3
c)
Let the lockbox drop down in the top slotted holes now,
and then install the bottom two screws. Tighten them
completely.
d)
Go back to the top screws and tighten them completely.
e)
Check that all four screws are tightened and firmly secure.
WARNING: It is imperative when tightening the screws that
the process has not deformed or twisted the vault box. The
installation surface must be flat.
