Why Our Customers Love Mail Boss

We are very happy with our Mail Boss mailboxes. We made an aluminum stand for them and put on combination locks (no keys!)

Best purchase I ever made. I mounted the box to a post I had from my old box mounted in concrete with house numbers attached.

I wanted to write and say how much I love my Mail Boss mailbox, lock lubricant, inground post and lock cover that I ordered directly from mailboss.com.
