            Please click on the following link for detailed installation instructions: https://www.mailboxes.com/assets/1/6/inst_verticals.pdf?49110 We hope this information is helpful. Thank you!

              1. If a recessed unit, create a rough opening in wall per dimension in Rough Opening Table. Units must be securely supported by a frame constructed of 2”x4” lumber. 2. Remove unit from carton and place it 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.
