            Does the flag come already attached, and if so, when you remove it, will there be visible holes in the side of the mailbox?
            ByNov 22, 2024
            1 Answer | 
            Answer This Question

            The flag is not attached however, there are two threaded pegs on the side and not holes.

            By|Dec 4, 2024


              Can this unit be inserted into a stone column with the flag still attached and operable? What would you recommend the reveal be, if inserting into a column?
              ByNov 21, 2024
              1 Answer | 
              Answer This Question

              You would not be able to fully insert this with the flag, you would need to allow room for the flag to operate, meaning the mailbox would have to protrude out.

                I'm thinking (out of the box) along the line of mounting this mailbox against a wall. Can I, say, put up a shelf on the wall and screw the bottom of the mailbox onto it?

                If that is what your post office will approve, then yes only use the bottom predrilled holes for mounting. We do not suggest drilling any other into the body as you will expose the metal and have potential rust issues.

                    Architectural Mailbox with matching Architectural Post are quite the dynamic duo. Very easy to install and I chose to decorate the bottom with some rocks which set it off nicely.

                    Weak
                    After 5 1/2 years the door broke. My 11 year old son opened it and the internal security bracket broke off. Unfortunately a contractor installed it (I selected it from Home Depot) so no receipt, which means no warranty coverage.

                      It is quite a decent and sturdy mailbox. It arrived on the expected day. There were minor puncture wounds in the exterior cardboard box, but the mailbox itself was in perfect condition. The keys worked well, once we learned the technique of specifically using the key tip to push aside the key slot's weather-sealing door. The local hardware shop had suitable key blanks (ILCO 1041T/CG16), so we were able to create 3 more copies immediately. The delivery door's security panel/system is quite good. We've played with other models/brands systems and we haven't managed to defeat this one yet. In fact, it's almost too good ... see the "one tiny thing" below. As the photo shows, we chose to mount it on 3 pieces of 1.5 inch EMT, screwed into 1.5 inch pipe flanges which we screwed to the box's bottom. We put acorn nuts inside the box to protect the mail from the screw ends. If there was one tiny thing i'd add/change, it would be to have some form of discreet (i.e. subtle) method for flagging that there was mail *in* the box. Such a feature would be "fiddly" to implement, so it really is unrealistic to expect one. Sometimes it's possible to tell by carefully starting to open the delivery door, and hearing/feeling the mail flop to the bottom of the box. Even when the mail is perched partially like that, it's impossible to see or reach without the key. If the mail carrier re-opens the delivery door after inserting the mail, even this "detection system" is thwarted and there's no way to tell if there's mail in the box. We chose this larger size to handle packages and tabloid-sized magazines. It swallows them all. The design is well-shielded against rain and wind, and includes rubber seals around the doors.

                      This journey started out with a postal delivery person that would not do her job, liked scanning packages as "delivered" without even being on my street, & making a habit out of not leaving these "delivered" packages with the mail! After purchasing a "Reolink Argus 2" wireless camera & solar panel, putting it up & showing video evidence to Amazon what she was doing, that got her in the mood to actually do her job as she's paid to do... !!! Since our mailbox was 30 years old, ugly, and small... decided to treat ourselves, & her to a nice, big, secure drop box!!! Since more & more is online & having to be delivered this was an excellent investment. Between this 48+ pounds of steel & wireless camera, think all the bases are covered for today's circumstances!!!

                      We bought this mail box because we had two incidence of mail theft. We live ten miles out of town and on a dead end street and have never had a problem until recently. We did the research and selected this mail box because it was large enough to get packages as well as good reviews on security. We get a fair amount of rain and it also handles that well. We got extra keyes made so that we can put them on all of our key rings. The mail box is 1/8 of a mile down from the house. We got some lettering made for the address and installed the mail box on the stand. That part took just a few minutes. We are delighted with the stand.

                      Great for mailbox column
                      I wanted a mailbox that would lock and accept packages. I was concerned the oasis would be too big looking, but concerned the oasis jr would not hold enough mail or accept large enough packages. The oasis was a good choice for my stone mailbox column.

                      this mailbox is great. I had no problems putting it into my brickwork mailbox.
                      This mailbox is built very well and is easy to incorporate into my brick mailbox stand.
