    Probably, but without knowing which post made by Architectural Mailboxes you are considering, I cannot say for sure.

      It says it's a combo of aluminum and steel. Is the door made of steel?

      The door is aluminum. The body of the mailbox is steel.

        I bought this mailbox from HD, but I need a 9-inch wide platform for it. You seem to only sell 6-inch wide platforms. Any suggestions?

        Answer This Question

        The mounting board does not need to be as wide as the mailbox. This mailbox has an 8 wide recessed underside. Simply center the 6 wide board (or brackets) leaving 1 on each side.

            Does it come with predrilled holes for screws? If so how many and how far apart? Ex. 1 in center or 4 at 5"x5" square or 4 at 10"x4" rectangle or 4 at 6"x6" square.

                How easy is it to apply address numbers on the mailbox? The design looks like it might make number placement awkward. What size numbers would fit best? Thank you.

                Answer This Question

                There is 7 1/2" of space between the raised vertical features on the side of the Manchester Mailbox where address numbers can be applied. We suggest using 3" to 4" (height) numbers.

                  Installed in a masonry mailbox so could not add address numbers to side of the mailbox.

                    The mail box was chosen to replace the one that was by the green Save Rural Elk Grove sign. It kept getting bumped into and knocked down in that location. It is big enough to take most of the mail sent to us. I was really pleased to find the door was substantial metal, unlike the flimsy plastic one the previous box had. It has been in place for about a month and has stood up well to being a water-fight shield and being roughly manhandled by assorted folks jerking on the door.

                    Wrong dimensions, poor flag mounting
                    The box and lid are heavy construction and that is a plus, although I have to return it because somewhere along the line it had been dropped and the back corner is bent. I measured the dimensions and they are INCORRECT - the printed dimensions are H11" and W9.875" - that is the size of the door, which is much larger than the actual box. The box is only 8'H x 9.75"H. Also, in order for the flag to work properly, it has to be mounted backwards for it to stay up, unless you tighten it, but then it has to be pushed down instead of it freely falling down because it rubs the sides. I can see the flag would never be put all the way down by the mail carrier. I won't be getting the same box when I take it back.

                      Great product, solid, well built! Not a cheap, flimsy, steel box. Good value for the price. Installed about a month ago and no issues.

                      We had to replace our plastic mailbox and didn’t want another so we upgraded to this and it’s perfect! We will see how durable it is but it is very sturdy.

                      Not even a full year before starting to rust due to a major design flaw. When fully opened the hinged door bites into the base of the mailbox. Over the winter this has already caused rusting. See pictures.

                        Paint is chipping off MailBox door.
                        Going on 2 years and its time to put this MailBox to bed.... The worse mother's day gift I ever bought. Looks and feels like a good quality mailbox until it was put to the test. The top of the Mailbox door and both sides of the door / hinge area is chipping away. Should of left the 25 year old MailBox. Even the Mail Woman is laughing at me.
