Pass-through letterbox made of stainless steel
Through the wall
The B3 pass-through letterbox is the exotic one in our range. With its help, the inserted mail slides through an individually extendable shaft through the masonry directly into your house. Our throw-through systems are designed in such a way that no screwing is visible from the outside. After the shaft has been installed, the two cover plates are screwed together from the inside
Mailbox with and without audio/video
You can purchase the pass-through systems as a mailbox only, but also with a fully equipped audio or video door intercom system. With the complete systems, depending on the type of system, you also receive an audio or video internal call station. All our complete sets can be connected to any standard 2-wire cable. Installation and commissioning is child’s play and can be carried out in a few simple steps.
Regular maintenance is very important for your stainless steel mailbox system. We recommend cleaning your system every four weeks. In winter, and even more frequently for locations on waterways or heavily trafficked roads. Each of our systems contains a can of maintenance oil spray.
