    My mail carrier seemed to tale a perverse pleasure in leaving my old mailbox door open when it rains; this NEVER happened when the weather was fair, go figure. After complaints to the Post Office netted zero results, I decided to take matters in my own hands by getting a new mailbox that’s designed to prevent disgruntled mail carriers from taking out their frustrations on my mail.This product is just what I needed, whith a self closing door that stops the sort of malarkey that was going on, as well as a locking compartment to retreive the mail. it’s very sturdy and well built. I now have peace of mind, and foiled the Postal Postman!

    Just put it up so we will have to see how the mail delivery works. Installed it on an existing dual mailbox wooden post with no problems. Even came with a bit for drilling the lag bolt holes. I did add washers so the lag bolt heads wouldn’t dig into the paint when tightened.
    This is a heavy duty mailbox and should last for many years. Seems to be very well built and should be very secure. The locking door doesn’t fit tightly so I may add a neoprene gasket around it.
    Not sure how the clip is going to work out for outgoing mail. It will work with standard envelopes fine but would probably not work for small packages or CD/DVD mailers.

    We have recently been victims of mail theft (and identity theft). We’re trying our best to stay one step ahead of thieves and purchasing this mailbox has made our situation a little easier. We spent time reading reviews on all types of mailboxes and this one stood out to be the best one in quality and price. When we received it, we knew immediately we purchased a very well-built mailbox! We added concrete at the bottom of the mailbox post to help with stabilizing it as it is definitely heavy duty. There is no way anyone can reach into it and take the mail and I think it would be even more difficult to pry open the lock. This is a great mailbox and looks great also…I think it’s the best looking one on our street!

    I purchased this product because the post office wouldn’t consistently hold my mail as requested. The box came with the proper hardware and wasn’t hard to install. Unfortunately, I had to tape a note to the door of the box because the postal carrier wasn’t pushing the mail towards the back of the box for the mail to drop properly which caused the door to stick in the open position. My only negative comment is that I was shocked that such a high-quality steel box has a flimsy plastic flag to alert the postal carrier to pick up mail. That seemed to be a poor design unless they don’t expect it to be used. My assumption is that it will break within the next few months and need replacing.

    Two nights ago, thieves pried open our neighbors locking mailboxes. They were unsuccessful with our Mail Boss, though not for lack of effort. They pried in at least 4 places, but it held. So far it has been knocked 10 feet off the post into a large tree with only a small ding, and now has foiled thieves. Other than an obvious bend where it was pried near the flag, it looks fine.
    This is an excellent product.

    We recently heard of mail being stolen in the neighborhood we moved in a year ago. I had been putting off getting a locking box for a while since the one we had was fairly new, but decided now we needed one. Looked at many models, but most allowed a hand to go through it to the mail, but this one does not. It only took my husband a few minutes to install on our old wood post. It is very sturdy and comes with 3 keys. I am very happy with this purchase.

    LARGE LOCKING MAILBOX
    THIS IS THE THIRD ONE I HAVE BOUGHT, RECENTLY MOVED AND GAVE ONE TO BROTHER,
    THESE ARE THE BEST AND TOUGHEST EXTERIOR MAILBOX OUT THERE,
    MY MAILPERSON GAVE IT A THUMBSUP AFTER SEEING IT, NO IDENTITY THEFT HERE WITH STOLEN MAIL,
    CONTINUING TO USE THE STANDARD NON LOCKING BOX IS LIKE PUTTING ALL YOUR IMPORTANT PAPERS
    IN A SHOE BOX ON THE STREET CURB FOR ANYONE TO BE ABLE TO ACESS THEM,
    THIS LARGE SLIDING SLOT IS BIG ENOUGH FOR A BOX OF CHECKS OR SMALLER PACKAGES TO BE SLID INTO SECURITY

    REGISTER THE KEY AND THE MANUFACTURE WILL SEND YOU NEW ONES IF YOU LOOSE YOURS

    I do love this mailbox! I’m very concerned about identity theft and theft of mail in general. I saw a video on you tube of someone trying to break into this mailbox with no luck. I compared it to other similar mailboxes from other manufactures and this one is the one I chose. Once I got it I can see that it’s going to live up to it’s expectation. Solid metal. I love the lock as well, it seems a notch above the standard basic “locking” mailboxes. Mounted in less than 30 minutes!

    Mail Boss has thought of everything. The quality and design and price are great. From the heavy gauge steel, non pry door, security key, heavy non pry non bend latch and baffle door to the supplied hardware even a drill bit came with. There is no other mailbox on the market that can match this box for the price. Far better than the Oasis Jr. for the same price. Oh, and free shipping. Bought one for myself and one for my daughter.
    Awesome.

    I have had my mailboxes over the years damaged and stolen. I researched and bought this box and matching post. It is well built and likely one of the best on the market, however, where the bolts screw through the bottom of the box into the post, the bottom Sheetmetal has flexibility do to it’s gauge and can be flexed when installed. Therefore, if someone rocked it back and forth enough, you could tear the bolts through the Sheetmetal. If it had a stiffening plate mounted on the bottom of the box, it would be greatly improved. Other than that I’m happy.

    I looked at many different mailboxes before settling on this one. It is a good value for the money. It is made of thick gauge metal and the lock tab has a hook on it to make it harder to pry open. It came with 4 bolts and a drill bit for installation. Installing it on a wooden post was easy and quick. It is a good quality product overall, I’m very satisfied with this purchase.

  12. Carl

    Bought the mailbox online to save $75 over the local hardware store that had them in stock, and it only took about three days to deliver. Because it weighs over 20 pounds, I put an additional “L” bracket on my wooden mailbox stand, which was easy and cheap if not 100 percent necessary. Installation instructions are easy to follow, and the company even includes the correct size drill bit for drilling the needed holes. The only thing I would suggest is that buyers purchase the graphite lock lubricant if they don’t already have some, and be sure to register the product online in case of any issues.

    I have been having trouble with my mail being stolen. I looked several places for a locking mailbox, but this was by far the very best I found. Esp. the locking mechinism. It was a higher price than what I had hoped to pay, but in the end it was sorth it for the peace of mind that they cannot easaily steal my any longer.

  14. GD

    Love this mailbox, all the neighbors in my court have come by and asked about it, and I know several who will also buy. I went to the Mail Boss website and found the matching post, slid it over my already concreted post and bolted it on….It looks spectacular, everyone should have this mailbox!

  15. Jerry

    This locking mailbox allows us to leave for the night (or 2) and not have to be concerned about unattended mail. There’s more then enough space for letters, magazines and small packages.

  16. lek

    Love it. Very well made easy to get mail out. The post person love it too. The little over hang is great for rainy days and the wide handle getting the mail in is great.

  17. gunn

    I live on a rural road and my house is quite a way from the road. My mailbox just seemed so vunerable so when a new pipe fence with no climb wire was installed it seemed like the perfect time to upgrade my mailbox. I had the box mounted to an antique iron wagon wheel and it looks amazing. I wish the dust cover for the key hole was not an option but came with the box. Spending $100 on a mailbox this should be standard. As long as my mailbox keeps my mail dry this winter I should be good to go (rain in CA is debatable).

  18. IanH007

    As discussed mailbox is good quality, no issues.
    Mounted in brick pillar as is common in Dallas-Richardson-Plano area in Texas.
    To remove flag before install use 1/4 or 8 mm socket, screw is double locked and very tight unless you remove nut first.
    Lockable Door requires clearance below box, check when installing or door wont open.

  19. Duchess

    My mailbox was destroyed by someone speeding in my neighborhood. I feel the cost is reasonable and well spent. I love this mailbox!! It is durable, secure, and made of quality materials that will not rust. Your mail will not get wet and you do not have to worry about it being stolen. The mailbox is heavy and you definitely need a good post to support it. If I move, I will take the mailbox with me-it’s just that good.

    Solid Constrution.

    Would recommend getting the following if mailbox will be installed on to a 4 x 4 wood posts :

    PostMaster Universal Steel Mounting Bracket

    Item #: 386582 | Model #: LUMBS0B06
    Holes align so no need to drill holes.

    Only drawback is keys are proprietary and cannot be copied.

  21. lucky

    We had mail and medicine stolen from our mailbox three times in the last 5 years. Since purchasing this locking mailbox, our mail has arrived without any problems. We feel safe if we aren’t home at the exact time the mail is delivered. Great purchase and worth the money!

  22. DIYer

    Overall good mailbox. It should withstand the weather for a long time. It also seems to be built with a heavier guage steel than the others I typically see in the neighborhood.

    Cons: flimsy plastic red flag that should have been made of steel to last; higher cost than some other comparable boxes; this model doesn’t come with the easy to use detachable bottom plate that is shown on the installation video even though they both have the same model name.
