    After installing this Mail Boss Mail box, I noticed everything on it was well made and solid, except where the box mounts onto the metal post I purchased to go with it. The four bolts screw through pre-made holes on the bottom of the box, but the bottom of the box has no re-enforcement plate where the bolts screw in, leaving the box able to flex slightly and could be rocked back and forth enough to tear through the bottom sheet metal. The entire reason I purchased this type of box was because I have had a lot of damage to my mail boxes and theft, over the years. This one is one of the best for security mail boxes I found, but If I could improve on anything, it would be re-enforcing the bottom plate. Other than that, I am happy with it.

    I received the post with a big scratch near the top. Poor quality control. Most likely, over time will rust at this area.

  3. Walkergin

    Sturdy post which goes well with the Mail Boss mailbox

  4. DEW

    I measured properly for new mailbox, dug a hole and set the post in cement. After one day, the post is solid, does not move and looks really nice. I like it.

  5. Rich

    Solid and secure. Good locking device. Able to receive small packages. Good instructions.

  6. LeisureCoach

    Very sturdy, complete installation instructions compatible with usps requirements

  7. Joeblow

    The post stated that it would accommodate most mail boxes. The mail box that I purchased with it didn’t fit an I had to drill holes into the box to make it fit.

  8. Sculptureca

    The post is hallow. The mail box it huge and It is perfect in every way. Only exception are the holes in base of mailbox for bolts not users leave holes on bottom of mailbox that rain could wet mail.

  9. Brad

    Easy to use but too short. Attaching the mailbox made everything very top heavy. Even with putting QuickCrete in the hole it still might be unstable.

  10. Denver

    Made installation very easy, pair it with the same brand mailbox and you will not have to get brackets or anything else.

  11. Reggie

    Fantastic quality! Looks great she lives on an extremely busy street and she is now safe getting her mail from the back.

  12. Sharon

    I put a 4×4 in to go deeper in ground used 3 bags of quikrete this thing not going any where
