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.
