Letterbox units – surface-mounted

Probably the most commonly installed type of letterbox unit is the so-called surface-mounted unit, sometimes also called a wall unit. As the name suggests, it is mounted directly on the plaster, meaning the letterboxes are fixed to the wall itself. The individual letterboxes can be arranged flexibly: you can have your letterbox unit laid out vertically or horizontally to make the best possible use of the available area, even where space is tight. If you are looking for a reliable partner in Berlin to plan and install your master key system, Fair Schlüsseldienst is the specialist shop that will be happy to do this for you. Of course, we make sure that all DIN standards are met and that the surface-mounted unit is installed professionally and in a space-saving way.

Upgrade your surface-mounted unit

Surface-mounted units can of course be used purely as a letterbox system. In addition, this type of letterbox unit is also available with various extra functions. For example, doorbells, engravings or video elements can be integrated. Here too there are many options, which can be chosen individually to suit every need. You can choose, for instance, whether you want individual buttons or a complete button module for your doorbells. Even buttons with special vandal protection can be integrated. Engravings are also available in colour and backlit, among other options. Our staff at the shop in Berlin Prenzlauer Berg will be happy to give you detailed advice, so that your building gets a surface-mounted unit that meets all your functional needs, guarantees maximum security and still blends elegantly and stylishly with the design of your property.
