The Classic all-in-one mailbox and post combo is as convenient to install as it is functional. The medium capacity lends ample room for your parcel deliveries and its double-walled plastic construction provides extra protection. The combo features an ultra-violet inhibitor finish to resist color damage from the sun. A back door allows you to retrieve mail without entering the street making it ideal for high traffic areas. The Classic can easily fit over an existing 4x4 post for a fast ready-to-use installation.
