About Here’s how it works: When you’re ready to receive packages leave your empty Package Box door slightly open, and the mail/parcel carrier will open the door and insert your package and mail. The carrier then SLAMS the door so that it locks (it shuts easily). You can then retrieve your package with your key. Another option is to set it up as a giant mailbox when you add the optional slot and/or flag. Specs Exterior Dimensions(H x W x D) 18″ x 18″ x 23″ Weight 165 lbs.
