Metal mailbox topper is cut from steel about as thick as a nickel. Tabs are bent for easy attachment to mailbox. This mailbox topper fits onto standard mailboxes and looks size-appropriate on large boxes as well! Sign has been powder-coated matte black for a durable and long-lasting finish. We do not manufacture or sell complete mailboxes. Your order will not include a mailbox. You will need to drill 2 holes into top of box, so washers are required to prevent moisture from entering mailbox. Hardware to attach to mailbox is included in your order. The mailbox topper is designed so you could also attach it to a wood fence or railing. All of our products are 100% made in the United States and made to last.
