letterbox stainless steel pass-through B3A-DW

The letterbox stainless steel pass-through B3A-DW 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 intercom is the non-illuminated and waterproof bell push.
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.

prepared intercom station

The paging system is supplied with a prepared paging station for your existing audio unit and indoor paging station.
For this we need the data of your system, which you can easily provide during the order process.
Accordingly, we prepare the front panel with the required welding studs. After delivery, all you need to do is attach your electronic components.

Alternatively, if you do not need an intercom system, we can stick the call station with black plastic behind it.

Cleaning the letterbox stainless steel throughput B3A-DW

To guarantee the high quality and durability of the entire letterbox system, regular cleaning and maintenance is very important.
In the scope of delivery you will receive a can of cleaning agent with which you have to clean the system every 4-6 weeks.
Care is particularly important in the winter months or when you live directly by a body of water.
