Frequently Asked Questions

What are the differences between the various categories?

The main distinguishing feature is the way in which the mailbox is mounted.

For example, Flush-mounted and Pass-through mailboxes are both inserted into a wall. However, a pass-through mailbox is recessed into the opening of a wall so that you can conveniently remove your mail from the inside of the wall. Meanwhile, flush-mounted mailboxes are simply installed in a recess in the wall, allowing you to remove your mail from the outside.

Surface-mounted mailboxes, on the other hand, are attached to the wall.

As the name suggests, Fence and gate mailboxes are designed to be mounted on or within fences.

Alternatively, there are also Free-standing mailboxes that are anchored to the ground with their legs.

In the Parcel box segment, we offer several different products, for example the Smart parcel box and the F-05 XXL wall-through parcel boxes. While the latter is installed like the pass-through mailboxes already explained above, the Smart parcel box is designed for surface mounting, but can be placed on the floor depending on your intended use. This is a good solution for contact-free delivery, which is especially attractive in times of pandemics.

I need a customized mailbox?
If you have special wishes for your desired product, simply send us an inquiry with your specific ideas via e-mail and we will create an individual offer for you. The delivery of a special order behaves differently to that of a standard delivery. In order to adapt the mailbox to your needs, it will be made separately. Therefore, the delivery time is 4-6 weeks.
Does the mailbox I want comply with the EN 13724 standard?
This so-called letterbox standard regulates exactly how letterboxes must be designed throughout Europe in order, for example, to be able to deliver your mail without problems and without being bent, to store it and to keep it dry. Mailboxes that do not comply with the standard can also be a reason for rent reductions. Consequently, you will save yourself a lot of trouble in the future if you keep the standard in mind when choosing your mailbox. The mailboxes in our offer usually comply with this standard. If this is not the case, this is explicitly noted in the corresponding item description. We also offer mailboxes that do not comply with this standard, because often the structural conditions simply do not allow a standard-compliant mailbox. With mailboxes that deviate from the standard, we want to give our customers the highest flexibility in the selection.
What does the optimal care for your mailbox look like?
Basically, the gentlest possible cleaning is recommended. We recommend (lukewarm) water with appropriate additives, such as household cleaners. It is particularly important to avoid substances that dissolve oxides, contain vinegar, propylene carbonate, mechanical substances or acetone, as these can damage the surface. After cleaning, sealing with car wax is also highly recommended.If you have a stainless steel mailbox, you should remove any residues. Again, cleaning agents containing chlorides, hydrocarbons or hydrochloric acid should be avoided. Special cleaning agents, such as stainless steel cleaner spray, are recommended for cleaning. In addition, we strongly advise you not to use steel brushes, steel wool or similar when cleaning your mailbox, as in the worst case these tools can destroy the surface and cause increased corrosion of your mailbox due to abrasion of the extraneous rust. When building your new home or renovating a house, the building materials lime and cement are omnipresent. These are anything but beneficial to your mailbox. Therefore, protect your mailbox from these substances by organizing a suitable cover.In the case of mailboxes painted in RAL colors, you can purchase matching touch-up pens, which can be used to repair minor defects. Do not use hot water in cold outdoor temperatures, as the high temperature fluctuations can put excessive stress on the paint, causing cracks. Apart from that, our painted mailboxes are to be maintained in the same way as the stainless steel mailboxes.The locks and hinges should also enjoy regular care. Use only non-resinous oils, such as graphite oil. These prevent loud squeaking and provide a certain ease of opening and closing. It is recommended that you do this at least twice a year. Before the onset of winter, it is best to treat your lock with a de-icing spray to prevent the lock from freezing.

What is important in a pass-through mailbox?

The correct installation of the pass through wall mailbox deserves special attention . In the beginning it is very important to find a suitable place for your pass-through letterbox on the one hand and to create a correct opening on the other hand. Adjust your mailbox to the desired depth and fix it with the supplied aluminum adhesive tape. Slide the insert into the breakthrough, bring it into the desired position and now screw it to the front panel. At best, wrap the part of your system that will be installed in the wall. We recommend filling any gaps between the letterbox and the wall opening with construction foam. Make sure that the resulting pressure does not deform your letterbox. You can safely cut off any excess material once it has dried. Now attach the panels, which are fastened with a simple clamping mechanism. Make sure that the rubber seals fit exactly to minimize water penetration. These sides are then grouted with acrylic. In the final step, install the plaster cover frame, if applicable, and seal any gaps with acrylic, if possible, to ensure a flush overall appearance with the rest of the wall surface. If protective films are still attached, you can now remove them.
