Mounting hardware is not included with our post mount mailboxes because the type of hardware needed is determined by the post type the mailbox is being mounted to. Mailbox mounting hardware is included with all new Architectural Mailboxes posts and 4x4 wood-post adapters.
If you are using an existing post, not made by Architectural Mailboxes, please reference the mounting hole diameter and pattern on your mailbox instructions sheet to determine the hardware you will need for installation.
