letterbox stainless steel pass-through B3V-DW-Maxi

The letterbox stainless steel pass-through B3V-DW-Maxi offers you the possibility to install your letterbox system completely in the wall.
We have deliberately kept the construction of the plant small and compact, so that it can find its place not only on the house wall, but also in smaller walls or fences.

Due to the depth-adjustable shaft, the B3 penetration fits into all common masonry.

Compact. Timeless. Noble

For our letterbox systems we exclusively use high-quality materials and components. In this respect, both the 450x500mm (WxH) front panel and the 450x250mm (WxH) removal plate are made of 2mm stainless steel 1.4301 and a vertical grind. The shaft is made of 1.25mm stainless steel 1.4016 and consists of two shaft parts that can be pushed into each other. This allows a variable adjustment of the required depth of 270-400mm.

After the shaft has been successfully plastered into your wall opening, the two cover plates are simply inserted and screwed firmly to the shaft with a few screws through the insertion shaft or through the removal door. No screw connection is visible from the outside. This gives you a clean and modern look.

We have adopted the flap from our B3 collection and with 350x80mm (WxH) offers enough space even for larger envelopes or newspapers.
Due to the slightly sloping course of the chute downwards, the inserted mail slides through automatically up to the 300x100mm (WxH) large and lockable removal door.

As standard we deliver each letterbox with 2 keys.

Lettering of your choice

Below the camera there is the non-illuminated and waterproof bell button as well as the intercom system.
Directly above this, we engrave your desired name deep into the metal structure using the latest laser technology, so that it is optimally protected from external influences and will still look the same for many years to come as it did on the first day.

Compact but large

Despite its compact dimensions, this letterbox system offers maximum space.
The total dimension of the visible front panel made of 2mm thick stainless steel is 350x750mm (WxH).
The flush-mount box measures 310x710mm (WxH) and is available in both 100mm and 150mm depth.

Both the insertion and the removal of the mail and newspapers are located on the front panel.
Envelopes up to size C4 can be easily inserted via the 240x55mm (WxH) letter slot.
Removal takes place via the lockable removal door located underneath. 240x300mm (WxH).

Each letterbox system is delivered by us with two keys as standard.

After inserting it into the wall, you have to connect the letterbox to the internal station included in the delivery and your system is immediately ready for use.
