How to Install a Mailbox With an Aluminum Pedestal

Determine the location of your mailbox. This will dictate where your aluminum pedestal will be installed. Your mailbox must be located in the common direction of travel, typically on the right side of the road, according to USPS regulations. It must be situated so the letter carrier can access the mailbox safely without leaving her vehicle. The base of the mailbox should be between 41 and 45 inches from the ground and the front edge of the mailbox should be at least 6 inches back from the road.

Measure your aluminum pedestal. Subtract the height of the mailbox from the length of the pedestal to determine how deep a hole you need to dig to support the pedestal. Dig a hole 1-foot square, and deep enough to handle your measurement.

Place your aluminum pedestal into the hole. Fill the hole with concrete. Use a level to make sure the pedestal is straight, then stake it with supports until the concrete cures. This may take from 24 hours to several days, depending on the concrete and weather conditions. Cover the concrete with dirt once it has cured. Remove the support stakes. Attach the mailbox to the aluminum pedestal.
