Powder-coated electro-galvanized steel construction makes this Mail Boss® Package Master® an ideal solution for identity protection. The durable mailbox comes with an anti-fishing mail receiving slot that prevents prying hands from reaching the post inside. It is only large enough to slip in an envelope, but can also take in packages with a slide-in movement of the door. However, one may not reach in with the hand if they wanted to pick up the mail lying inside. The wafer lock on the door of the mail retrieval compartment prevents any kind of forced entry, so you can access mail only by unlocking the door. The Package Master mailbox is easy to set up as it can be mounted on existing post or Mail Boss In-Ground post.
