The Classic 1? 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, including small boxes, magazines, and padded envelopes. 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 4-by-4-inch post for a fast, ready-to-use installation and comes with a five-year limited warranty for your peace of mind.
