Package Box Mailbox

18″ x 18″ x 23″ at 165 LBS. (Box Only)

Designed for many purposes — including storing large packages. The most popular setup of the Package Box is using the included “Slam-Lock”. Leave the door slightly open, and the mail carrier will open it and insert your package and mail. They then “slam” the door so it locks. Retrieve your package with your key. Another option is using it as a giant mailbox, if you add the optional slot and/or flag.

The Package Box comes standard with one solid front door and includes a Slam-Lock with knob. Adjustments can be made as some pictures on this page represent. Some photos show an added flag and mail slot for making a very large mailbox and package box all in one.

Contact us if you need a specific size.

Matching In-Ground post for this mailbox is: LG 5″ x 5″ x 57″.
