I installed this in my new treehouse for the kids. It is very solid and I bought this one because it was so sturdy that it will hold up with lots of kids getting heavy use out of it.The outside has a double door to keep the rain out when the mail is dropped in. The mail falls down a diagonal shoot into the box on the inside. You need to enter your own chosen security code to get the box open. The security code is very easy to set with your own chosen numbers. I highly recommend this mailbox for the quality and durability.
