2. Remove unit from carton and place in an upright position on a
table or other flat surface.

3. Remove the compartment assembly from the frame by tilting the
compartment assembly forward until it extends approximately two
inches from the frame. Then lift the compartment assembly upward
so that its base clears the hinge pins located at the bottom of the
unit. Swing the lower end of the compartment assembly outward and
remove it from the frame.

4. Mount the frame in the desired location. Caution: Do not deform,

force, or twist the frame to fit an incorrect rough opening or
irregular surface. If the frame becomes deformed, it will not retain

proper alignment with the compartment assembly. Units serviced by
the United States Postal Service must be installed with the master
lock opening a minimum of 30” and a maximum of 58” above the
finished floor.

5. Replace the compartment assembly into the frame, reversing the
procedure in step 3 above.

Security Caution

The tenant door at or near the center of the compartment array, in
addition to providing access to a tenant’s mail, also provides access
to the USPS Arrow Lock that provides access to all compartments.

For the sake of security of the entire compartment array, it is
important that this tenant door be securely locked at all times,
even if there is no tenant receiving mail via this door.

Arrow Lock Guard – 3500 Series

Installation Instructions

IMPORTANT !

After installing the mailboxes, contact your local postmaster – the
USPS will provide and install its own master lock on your mailbox

unit. Hardware for installing the master lock is included in the

plastic bag. Please provide the hardware and these instructions to

the USPS representative when they arrive to install the lock.

INSTRUCTIONS FOR THE USPS REPRESENTATIVE:

1.) Unlock and open the door marked ‘U.S. MAIL’, and pull the
top frame forward, exposing all of the mailboxes.

2.) Remove the Key from the Arrow Lock so the lock’s bolt is
extended.

3.) Rest the Arrow Lock on the pre-installed Lock Bracket
BOTTOM TAB with the bolt facing up and the keyway
facing outward (see sketch at right and Photo #3).

4.) Insert the key through the large hole in the Lock Bracket
and into the Arrow Lock, and then turn the key so the bolt
retracts. Now push the lock into place under the Top Tab of
the Lock Bracket (see Photo #4).

5.) Insert the two long screws through the Lock Bracket holes
and through the holes in the Arrow Lock (see sketch). Do
not attach the nuts yet.

6.) Place the Lock Guard (Photo #6) over the Arrow Lock so
the long screws are through its holes, and the Lock Guard
rests on TOP of the frame (as shown in sketch).

7.) Attach the Lock Nuts to the long screws and tighten using
a Phillips screwdriver and an open-end or socket wrench.

8.) Screw the short Self-tapping Screws through the Lock
Guard and the holes in the frame.

9.) Push the frame closed.

10.) Turn and remove the Arrow Lock Key, locking the unit.
Close and lock the ‘U.S. MAIL’ door.
