4C Recessed Mounted Horizontal Mailboxes – Wall Framing
Installation Instructions
ROUGH OPENING DIMENSIONS
Each unit requires a separate opening in the drywall. Each pair of units
will have a 2x4 stud separating them. The trim frames cannot be butted
together. There will be a space between edges of trim frames of approxi-
mately 3/4” when 2x4 studs with drywall separate the mailboxes.
CALCULATION OF SPACE REQUIRED FOR MULTIPLE MAILBOXES
For overall width of mailbox installation, add up all of the stud spacings
and subtract ¾”. For overall height of units, see the dimension chart
below.
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 tight-
ened between the frame and the studs. Studs must be installed plumb
and square to further ensure proper fit and function of the mailboxes.
Construct wall and mailbox support structure with drywall, 2x4
lumber, and 3/8” plywood. 2x6 lumber may be used for a stronger
wall.
Cut a hole(s) in the wall according to the rough opening dimen-
sions. Each mailbox unit assembly should have its own opening
in the drywall.
Place unit(s) into rough opening(s). Open the carrier access door
and open the front doors by lifting the latch handle on the left be-
hind the carrier access door. See illustration on page 1 for location
of carrier access door. Note the mounting hole locations and drill
pilot holes into the studs. Securely fasten to the support framing
with the screws provided. See illustration below. Install screws
into all holes provided in both right and left side vertical trim frame
members.
Caution: Do not deform, force or twist the frame to fit an incorrect
rough opening or against an irregular surface. Do not overtighten
the installation screws. If necessary, shim the small space be-
tween the stud and the vertical, extruded aluminum trim frame.
Test all master doors, patron doors, and parcel locker doors to
ensure that they open and swing freely without binding or sticking.
