FAQs About In-Wall Mailbox Units

How do you install in-wall mailbox units? 

In-wall, or recess-mounted mailboxes, are installed within carefully measured openings in a wall. The mailbox is inserted into the opening and firmly secured using bolts and caulking to ensure a snug fit.

 

What is the difference between in-wall and surface-mounted mailboxes? 

In-wall mailboxes are recessed into pre-measured openings within the wall, offering a seamless and space-saving solution. Surface-mounted mailboxes are installed directly onto the exterior surface of the wall or post, protruding outward for easier access.
