The Hamilton decorative in ground post can support most mailboxes weighing up to 50 lbs. Made from cast aluminum, galvanized steel and then fully powder coated for added durability and corrosion resistance. This post offers a beautiful design with highly functional elements such as a telescoping arm that can be raised and lowered and also rotated 360 degrees. To finish this design it comes complete with a molded ABS fluted base to cover and protect the post from weed whackers and hide any unsightly concrete.
