be butted together. There will be a space between edges of trim
frames of approximately 3/4” when 2x4 studs with drywall separate

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.
Notes
1. Although these mailboxes have been tested and approved for
both outdoor and indoor use, some shelter from direct weather
conditions should be provided, especially in areas with heavy rainfall.
This provides protection for the mail, the delivery personnel, and the
mail patrons.
2. The mailboxes are shipped fully assembled.
3. Hardware is included to fasten each unit into a wood framed wall.
4. Trim is an integral part of the mailbox assembly. There is no other
snap-on trim to install.
USPS Regulations
The mailboxes must be installed according to Postal Regulations.
1. The floor of the lowest patron mailbox shall be no less than 28”
above the finished floor.
2. The patron lock in the highest mailbox shall be no more than 67”
above the finished floor.
3. The USPS Arrow lock (master door lock) opening must be a
minimum of 36” and a maximum of 48” above the finished floor.
4. The floor of the lowest parcel locker shall be no less than 15”
above the finished floor.
5. The master access door(s) must be allowed to open a minimum of
90 degrees with no obstruction.
6. There must be at least one parcel locker for every ten patron
mailboxes in installations of 10 or more patron mailboxes. There is
no requirement for parcel lockers in installations of less than 10
patron mailboxes, but one or more parcel lockers are recommended.
Installation Instructions
1. Construct wall and mailbox support structure with drywall, 2x4
lumber, and 3/8” plywood. 2x6 lumber may be used for a stronger
wall.
2. Cut a hole(s) in the wall according to the rough opening
dimensions. Each mailbox unit assembly should have its own
opening in the drywall.
3. 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 behind
the carrier access door. See illustration on page 3 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 over-tighten
the installation screws. If necessary, shim the small space between
the stud and the vertical, extruded-aluminum trim frame.
4. Test all master doors, patron doors, and parcel locker doors to
ensure that they open and swing freely without binding or sticking.
