          It should as long as the mounting holes are the same as what is predrilled on the floor of the mailbox.

              How much does the large mailbox weigh?

              Answer This Question

              Obviously I didn’t weigh it when I installed it, but I would estimate 2-3 lbs.  It’s been holding up good and still looks brand new.

                      Hello, there are many options available to you for custom lettering, which you can have done locally by a small business who can create custom vinyl lettering or you can order each character and digit separately to spell out your street number and name - we recommend using 2-3 inch numbers and letters. Thanks for reaching out!

                        Built in the dark!
                        Came nicely packaged and safe. The bottom plate was not installed correctly and is that such an angle that is visually unappealing. The flag was installed crooked, and there were several dents on the inside and out. I did reach out to HD customer service and they told me that I had 2 options. Return the item and re-order it which would take over 2 weeks or a 10% refund. So my options are have no mailbox for 2 weeks, or a $5 refund on an item that had too many problems to mention!

                          Avoid Red
                          The red fades drastically. My mailbox is in the open and faces all the weather elements. After a year the color was more like pink (picture included). The mailbox itself is really nice quality and sturdy. The paint used is not of great quality at all. I don’t recommend this in red.

                            Metal dents easily
                            Overall looks really nice. Metal can be dented easily so be careful. Read the other reviews about the color fading so we applied a thin layer of car wax. We just put it up a couple weeks ago so time will tell if it fades. Also the latch/magnet is a bit flimsy.

                            Shipping was handled well and timely (on time). The color was the most alluring...shiny, bright red metal box. However, after 7-8 months, it is fading. However, it serves its purpose.

                              Mailbox was delivered on time and was as expected. This was a good option for a more modern look and it also is able to hold small packages. Recommend buying the black base too as easy to install as it includes the necessary hardware.

                              Very happy with this purchase! It was a bit bigger than I expected but not complaining. I ordered the 4x4 post adapter with the mailbox which made installation a breeze. I also added a coat of car wax to preserve the red color here in the hot Florida sun. Others have complained about the hinge connection not being metal but I have not had a problem with mine. My mailman is very happy now.

                                This is a very nice, large metal mailbox. The color is very bold and here in Maine, that helps the snow plows see it when plowing the snow off the roads. The front has a nice firm handle attached at two points. The flag is also metal and moves easily. I mounted mine with the help of a short length of 2x8. I cut the wood to length and my plan was to screw that to the mailbox holder and then screw the mailbox on the wood through the holes provided along each long side. The problem with that plan was that the neighbor's mailbox is adjacent, on the same mailbox stand preventing access to one side to screw it down. So I changed my plan to fasten the mailbox onto the 2x8 first, then screw it to the platform from below. That worked fine but then I found the wood I used was too long and prevent the door from opening! So I had to undo it all and cut the wood shorter and try again. The instruction sheet did in fact mention one should check the clearance of the hinge! It was a quick mounting solution that is solid. There is a mounting plate that is sold separately. The inside of the base is 18½” long and 7¾” wide. The wood section below should be about 17” long. I applied some big yellow numbers which produced an excellent contrast with the red. Great looking mailbox, and it looks durable too.

                                Very nice and durable mailbox. The gauge of the metal is heavy duty. A magnet at the inside top of the door helps to keep it closed. Its a really nice red and great coverage with the paint to help protect the metal from corrosion. It is approved by the Postmaster General so it must be good. Ordered online and it arrived in excellent condition since it was packaged really well.

                                Great look and a quality mail box. Gotta love the bright red color of this box. It really stands out and adds a touch of class to a normally boring thing. Added bonus is now if expecting new friends I can tell them to look for the red mailbox. The box itself is a larger size and the construction is excellent. Loads of capacity and the door handle/flag is a nice silver which stands out. Very happy with my choice.
