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

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.
