Will it fit your door

The inventor David spent a lot of time thinking about how to attach the LetterBoxer to a door and examining the letter boxes of friends and family. He also spent many days looking at all the different door letter box designs as He walked to town through the long-terraced streets of Lancaster. In the end, he came up with a very simple solution.

How Do I Install?

Installing the LetterBoxer is an effortless process that can be completed in just a few easy steps.

1: The first step is to loosen your letter box plate using the screws on the inside. It’s important to note that there are many different configurations of letter box plates out there, and the screws may be located in various positions. However, in most cases, they can be found under the inside flap or mounted on the inside plate itself. 

2: Once the plate is loose, the next step is to slide the metal bracket at the back of the LetterBoxer over the back of the letter box plate. Ensure that it fits snugly and securely, and then tighten the screws.

3: Finally, lift the front of the LetterBoxer and attach the fabric side panel bracket lugs in the female slots. Slide them down on both sides until the LetterBoxer is firmly in place. And that’s it! Your LetterBoxer is now ready to use.

4: In conclusion, installing the LetterBoxer is a quick and easy process that requires minimal effort. With just a few simple steps, you can have a secure and convenient mailbox solution in no time.



EASY INSTALLATION – It cannot get any easier! It can be simply installed on any door within minutes without the need of special tools. No need for drilling holes and causing permanent damage to your door, either.

I Don’t Have A Letter Box Plate!

AAH yes, well, we did think of that, and we included four screws which can be used to fix the LetterBoxer to the door under these circumstances.  We made holes in the back of the LetterBoxer to put the screws through when fixing to the door in this way.

What’s the Extra Fitting That Came in The Box?

It’s just an alternative back bracket.  Some UPVC and older wooden doors have extruding mouldings which inhibit the default bracket fitted to the LetterBoxer. 

Also, some older doors have very little room above the letter plate, which makes it difficult to install with the default bracket.  This alternative bracket enables you to fit the LetterBoxer in these circumstances. 

We have included an Alan key in the envelope that came in the box, so you can swap out the back bracket with this extra one.  You can also use this key to adjust the fabric side panel lugs in case they come loose down the road.  So, keep it safe.
