I've installed mine through an exterior door, and I'm making a box on the backside to catch the mail. The fit and finish are excellent, and it's very sturdy. I read all the previous reviews and knew what to expect, so I'm very happy and gave it 5 stars. I've been looking for something like this for 2 years, and it just didn't turn up on previous Amazon searches, or I'd have bought one sooner.I went to the manufacturer's website and downloaded the PDF files for installing it. They are helpful. The installation was easy for me, but I'm a pro contractor with tons of tools.I like the large mail opening size that will accept large catalogs and medium sized packages. My homemade catch box will be sized to accommodate this, and catch a month's worth of mail. The opening is large enough for me to get my whole arm into it, so I'm making the catch box 48" high, so a thief can't reach my mail or packages, even if they pile up. Then I'm putting a 4" thick foam pad in the bottom. This exterior door opens into the garage, so the size and appearance of the box is not critical.I got my first mail delivery today, and my postal carrier really likes it. Most boxes require 2 hands to place the mail. One to open the lid, and one to place the mail. I noticed my carrier had one hand full of mail, for everyone on my side of the street. So, she loved that this box has a push in door, and only requires one hand to stuff the mail in. Something I'd not thought of until today. So, if you want to please your carrier, this could be another star in the star rating?

Excellent mailbox, well constructed, and am very happy with it.Now, to an actual review, and points:I recently bought a house, a condo actually, in a historic district, as such, the condo does not have a central mailbox system, as many are used to; so all mail-slots are built into the doors. Since I live on the east coast, the weather out here is very cold in winter, and very hot in the summer, which basically was blowing out all my heat out of the ground portion of my house! I was very annoyed by this as you can imagine.However, I have a small exterior utility closet one can call it, built into my property, right next to my door. It has its own door, which is lockable, and it is isolated/insulated from the interior. Most things were running through it are HVAC piping and so forth. So, I decided, instead of losing all this heat, due to drafts, I will remove my mail-slot from my door, fill it in with block of wood, and then sand it all down and paint it - and instead, put the Salisbury Mail Box/Slot into my "utility" closet door. It worked quite well - but please remember following points:1) If you doing custom installation - you should be handy with the saw, and in general handy with fixing, modifying and doing things to the product which were not intended.2) This is WALL MAILBOX designed unit. Which means that through a regular 2" - 3" (inch) door, the mail chute will be hanging off. If you wish to install an additional receptacle box, which Salsbury sells, you will have to cut the chute to size. To me, this was just silly, since I have a closet dedicated to mail.3) I had to drill through the Mail Box front bezel in order to correctly install it/hook it up to a 3 Inch Door. Not a big deal. I used the existing 2 screw holes as a guide.4) When you make the hole inside the door, remember that mail chute is SLANTED, which means you have to cut the opening slightly larger, and then shave of the booth portion of the opening at an angle, to allow the chute to install correctly. Once this is done, you can "bang it" into place using a block of wood as a buffer between the hammer and the mailbox. Additionally, then you can fill in the edge opening which will be inevitably left with a quality caulk.Conclusion:I am giving this mailbox 5 stars. It is excellent heavy duty aluminum construction. I think it is a great replacement for almost ANY mail slot out there.If you have to built this into your garage door, or main door, with some tinkering it can be modified to close very well, and prevent drafts. Since this is aluminum construction, I would have routed small area on the mail slot, and mail box bezel, and glue into the area high quality rare earth magnets. But I had a spare outdoor faceable closet, but option was still there. I have done tremendous amount of research, and for the size, quality of construction, and DIY options available - this is so far the best mailbox there.

We shopped around and took a chance on this mailbox. It's solid and we're very happy with it. It was secured to the garage so that our mail is dropped just inside into a large box. It closed with little slam because it's springy, but I just adhered a sticky strip of fabric to the inside frame where the box door hits to muffle the metal slam. The sound wasn't too bad, but the felt fabric softens the sound from the spring-loaded closure. It was a good purchase for peace of mind.

This is a well constructed product. We are going to put it in the wall next to our entrance door and have the mail drop into our entrance closet so we won't suffer any drafts or loud bangs. The instructions leave a bit to be desired, but one can get the idea. You do need to know how to cut stucco (or whatever your wall material is), drywall, and block out support for the mail slot. A good handyman should be able to do it in a few hours.The structure is well made, but the door doesn't have great positive closure force, so it may open and let strong breezes through. A spring loaded door would help that, or perhaps glue/weld a weight to the back side of the door. Just make it so the mail carrier can easily open and insert your post.The only other draw back is there is no real way to leave outgoing mail unless you physically attach something to the frame.Overall, a solid product that does what is intended.

This product is very well made. The large opening will accept small packages. It required quite a bit of work to install. It did not have a cut out template. I had to make one from cardboard. It did not have a backing plate. I had to make one from plywood. To cut the opening in the garage door I used a 4 inch angle grinder with a 6 inch cut off blade.

We travel a lot and needed a bigger PO Box at our house. My husband installed it easily and we even get smaller packages put in there. Very secure.

We did paint it white and put brick mould around it for new siding. Works perfectly!

Solid. Beware that there are no mounting holes or hardware. Not a big deal for me, because it's soft aluminum, but may be a problem for others. I suspect it may drip if not in a covered location.

We use as an external mail slot for clients to drop off documents when our office is closed or no need to enter the office (COVID)

Very easy way to add a mail drop slot to our new office. Item was as expected and arrived very quickly

Because our main entry doors are glass, we put it in the outside wall of our house. works great, nicely powder coated and looks nice, but it was difficult to install because of the angled shaft. Also the internal shaft wasn't wide enough to go through the entire outside wall, so we had to improvise, but it all worked out.. Works great as a mail drop from outside to inside.
