Important information
Camera or intercom preparation
The intercom systems must be connected by an electrician. Please contact your trusted electrician for planning, fitting and installation.
Water protection
The mail is only protected against moisture and dirt when it is fully inserted and the flap is closed. Under certain extreme weather conditions, water may still enter (up to 1ccm according to DIN EN 13724). This is not a reason for complaint.

Frequently asked questions about letterbox systems
If your letterbox is in its original packaging, your keys are in the letterbox (take them out through the insertion slot) or in the enclosed bag (this also contains the assembly aid and other small parts). Every letterbox that leaves our premises is carefully checked and packed. A declaration of care is enclosed by the employee who manufactured your new product. If you still cannot find your key, please feel free to contact us.
DIN EN 13724
When planning a letterbox system, you should always observe the currently valid DIN EN 13724 (also known as the ‘letterbox standard’) so that you or your tenant do not have any problems receiving post.
DIN EN 13724 guarantees you:
• Easy mail delivery without bent letters or personal collection at a post office, e. B. for large DIN C4 envelopes
• Sufficient storage space for higher mail volumes
• No hassle with wet mail
• Best quality through specified and tested materials
• Security against rent reductions through standardised letterboxes
Our products are usually all tested according to this standard and marked accordingly. Only a few do not meet this standard. Find out more

Information about DIN formats that fit into the corresponding letterbox slot is cropping up more and more often. Here is a brief overview of the dimensions of the most common formats:
DIN A5: 148 x 210 mm
DIN A4: 210 x 297 mm
DIN A3: 297 x 420 mm
DIN B5: 176 x 250 mm
DIN B4: 250 x 353 mm
DIN B3: 353 x 500 mm
DIN C5: 162 x 229 mm
DIN C4: 229 x 324 mm
DIN C3: 324 x 458 mm
1.4301 is characterised by its good weldability with electrical processes. Even without heat treatment, the steel is corrosion resistant due to its low carbon content. The carbon content must be below a percentage of 0.08, although values below 0.05% are now common in practice. It can also be polished very well and is flexibly formable. It is approved for temperature stresses of up to 600 °C. Its high-quality appearance is particularly appreciated when polished.
X5CrNi18-10 is a relatively soft, nickel-containing, non-ferromagnetic austenitic steel. To keep the material rust-free and scale-resistant, 1.4301 contains a minimum of 13% chromium.
We now use 1.4301 stainless steel for the majority of our products. Compared to galvanised steel, this has the advantage of increased durability and sustainability. Our claim for a manufactured product is that it lasts a lifetime.
The material 1.4016 is part of the stainless steel group and is also known under the designation AISI 430 or X6Cr17.
This is referred to as ferritic steel and has a maximum chromium content of 18% (minimum 16%). Ferritic steel is highly magnetic, unlike austenitic steel grades. The special property of stainless ferritic chromium steel lies in its ferritic microstructure. This is what makes 1.4016 resistant to stress corrosion, which is usually the critical point in austenitic stainless steels. The drawback is the poor weldability of the material.
The material is characterised by its good bending, deep-drawing and polishing properties. Its insensitivity to stress corrosion cracking and its basic resistance to alkaline solutions, moisture or diluted organic acids, for example, should also be emphasised. It is not resistant to corrosion in salt water.
We now use 1.4016 stainless steel for the majority of our powder-coated products that do not require welding. Compared to galvanised steel, this has the advantage of increased durability and sustainability. Our claim for a manufactured product is that it will last a lifetime.
Powder coating is a tried and tested method of refining our surfaces. In this process, electrostatically charged powder coatings are applied to the respective workpieces using a spray gun. The parts then pass through a conveyor system to be baked in the oven. At temperatures of around 180° Celsius, the structures of the powder and the coated surface bond with each other. The heating process gives the powder a high-quality, smooth or evenly structured surface. We powder-coat metal parts such as steel, stainless steel, aluminium or other electrically conductive materials.
The advantages of powder coating include high corrosion protection and strong resilience. Coated parts are impact and scratch resistant, as well as resistant to chemicals and weathering.
Powder coating is a particularly environmentally friendly surface treatment technique, because no solvents or thinners are used in powder coatings. In addition, the powder coating process saves resources because the excess paint that is applied can be reclaimed.
We use both terms interchangeably, so the abrasive rating of our products always corresponds to 240 grit. This number indicates the roughness/grain size of the abrasive. The surface is matt.
