Illustration 1 - Typical Installation

Preparatory Steps

1. Have mailboxes and instructions on hand before starting wall

construction.

2. Unpack and review contents of shipping cartons.

3. Gather tenant and parcel locker keys and store in a secure place.

4. Read installation instructions document thoroughly.

5. Determine rough opening size(s).

6. Determine rough opening location above finished floor.

7. Determine framing configuration and location.

8. Procure materials for wall construction.

Rough Opening Dimensions

Each unit requires a separate opening. Each pair of units will have a

2x4 stud and (2) 2x2 studs separating them. The trim frames cannot

be butted together. There will be a space between edges of trim

frames of approximately ¾”.

Calculation Of Space Required for Multiple Units

For overall width of the installation, add all of the stud spacings and

subtract ¾”. For overall height of units, see chart in next column.

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.
