This gives you an easy and practical rear door solution if you have an open cavity, but don't want or need an inner box.
A rear door and flange can be applied to most surfaces but is most compatible with solid surfaces such as brick or rendered walls or pillars.
Pair this with a mail slot on the front of your wall or pillar for a complete mail-receiving solution. You could also pair it with a custom faceplate to show off your street number and address.
All our letterboxes are made to order in North Plympton, South Australia. While we endeavour to manufacture as quickly and efficiently as possible, the standard lead time for a Rear Door with Flange is 4 weeks. Factory conditions change year-round, however, so no lead times can ever be guaranteed.
Colours seen in the colour selection drop-down thumbnails and in the product images are computer-generated representations of the powder coat colours. They are not 100% accurate to how the real-life colour will appear, they are merely a guide. Several variables such as lighting and the surrounding environment will have a big impact on how your chosen colour will appear in the flesh.

Measuring Guide
See below graphic showing how to measure for your rear door and flange.
You need to base your dimensions on the size of the cavity you have in your wall. The door should then ideally be 10mm less than the cavity both height and width. Flanges are usually 25mm larger than the door all around.
Example:
Cavity Size: 350mm wide by 150mm high
Door Size: 340mm wide by 140mm high
Flange Size: 390mm wide by 190mm high


Installation
The rear door and flange will feature a lip on the bottom row of the door for the lock to latch to. You will need to make sure that the cavity you install this rear door over will allow for this.
It is best to have an opening no smaller than the door size and no bigger than the flange size.
A concept drawing will be provided for you to approve after ordering. This is to ensure you are happy with all dimensions and the details are correct and suitable for where you are installing it before we manufacture.
