Flared ends that produce a one-of-a-kind appearance on the Callaway mailbox post will have the neighborhood in awe. The rust-resistant post is constructed from extruded aluminum, while the base is made from steel. The post is also adjustable to reach heights between 33 in. to 41 in. tall, providing maximum flexibility for homeowners. The post can be anchored to an existing 4×4 in-ground post or bolted to a concrete pad for extra stability. The Callaway post is designed for use with medium-sized to extra-large-sized mailboxes. It is available with a choice of black or white powder-coated finishes that help extend the post's longevity.
