Our mailboxes are designed to be a wall-mounted mailbox. If you are exposed to elements, the mounting holes prevent the mailbox from being fully waterproof; so, we recommend purchasing this sealing kit. The sealing kit will cover the mounting holes with a special rubber washer (3X) and we will add a sealing gasket in the back of the mailbox to seal it with the lid (the gasket will be already installed).

****WE CAN'T SHIP THIS ALONE; IT NEEDS TO BE PURCHASED WITH A MAILBOX.

If you have any questions, don't hesitate to contact us.
