Letterbox stainless steel pass-through B3V-DW-Mini-HF

Through the wall

The letterbox stainless steel pass-through system B3V-DW-Mini-HF offers you the possibility to lay your letterbox 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.

Labelling 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.

completely preconfigured

The video system is completely pre-installed and configured by us. 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. The modern technology of the video system allows connection to any existing 2-wire line.

The internal call station Mini Handsfree Video from Comelit offers a sharp view of your front door through the 4.3 inch screen in 16:9 format (480×272 pixels). Operation is via touch-sensitive keys below the display. The microphone unit is surface-mounted and can be mounted directly on the wall or on an existing flush-mount diode.

Via the optional Wifi connection you have the possibility to receive your door calls from any location via the downloadable app (Android/iOS). Not only the sound, but also the recorded image of the camera is transmitted directly and live to your mobile phone. You can also open the front door or the entrance gate remotely via the app.
To do this, you also need an existing WLAN network in your house.

Cleaning of the stainless steel B3V-DW-Mini-HF pass-through system

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.
