Also known as a mailbox anti-theft or anti-vandal chain anchor , this system is a surprisingly smart way to keep rural mailboxes standing tall — even after being hit by trucks, ATVs, or late-night joyriders.
The setup is simple:
- A short metal post holds the mailbox high above the road
- At the bottom of the post is a loop or bracket
- A heavy-duty chain connects the post to a concrete-encased anchor buried underground
So when someone tries to yank the mailbox off its post — they end up yanking their own bumper instead.
That chain doesn’t just hold the mailbox upright — it fights back.
