Wall Construction
Particular attention must be paid to wall framing to provide a strong
and secure attachment of the mailbox units. Stud spacing must be
accurate to ensure that there is minimum space between the studs
and the mailbox frame and minimum mailbox frame distortion when
the fasteners are tightened between the frame and the studs. Studs
must be installed plumb and square to further ensure proper fit of the
mailboxes.
