How to Install a NEW Mailbox and Post with the Slide Me Out™ Mailbox Bracket
Mailbox Location
The mailbox should be placed 6″ to 8″ back from the curb. If you do not have a raised curb, you should contact your local postmaster for guidance.
The mailbox should be positioned 41″ to 45″ from the road surface to the bottom of the mailbox.
Choose a Post
The mailbox post should be stable but bend or fall away if hit by a car or plow.
The Federal Highway Administration recommends a 4″ x 4″ wooden support or a 2″-diameter standard steel or aluminum pipe. Avoid unyielding and potentially dangerous supports, like heavy metal pipes, concrete posts, and farm equipment (e.g., milk cans filled with concrete).
Install the Post
- Contact your local post office for proper post hole placement rules and measurements specific to your town.
- Laws require calling Dig Safe at 811 before any digging to ensure you will not come into contact with underground wires or gas lines.
- Be sure to wear proper eye protection and gloves.
- Secure the digging area.
- Use a post hole digger to dig a hole for your post. The hole should be no deeper than 24 inches.
- Secure the post with 6 to 8 inches of crushed rock to support post and allow for water drainage.
- Test the depth of the hole by placing the post into the hole and checking that the height is between 41 and 45 inches from the road surface.
- Ensure post is straight and cross support is level.
- Finish securing the post by either:
- Fill hole with gravel and pack down to eliminate air pockets.
- Use a 50lb bag of concrete to secure the post. Use support beams to hold the post in place while the concrete is wet. Use a level to make sure the post is straight.
