Uncomplicated installation on almost any fence, simple harmonisation with the surroundings and additional space that was not necessarily expected – these are the indisputable plus points of fence letterbox systems. Bells and a communication system (both optional) round off the overall impression.

Fence mailbox systems. Briefly explained.

What is a fence mailbox system?

A fence mailbox system is a mail receiving system that is attached directly to a fence, gate or gate. The system is mounted or hung in such a way that it is accessible from the outside and blends harmoniously into the property boundary. KNOBLOCH offers several so-called rod mats for attaching letterbox systems to fences, which greatly simplify installation, especially for systems with rear removal.

  • Space-saving – the system utilises existing fence areas without taking up additional space in the entrance area
  • Good accessibility – delivery staff can easily insert the mail without having to enter the garden or the house. Mail is always inserted from the front and removed from the front or rear, depending on the model, i.e. from inside the property
  • Flexible positioning – letterbox systems can be installed at almost any desired location along the fence. For systems with bells and a communication system in particular, installation close to the access routes is of course recommended
  • Quick installation – Comparatively little construction work is required, as only a sturdy fence or grille is needed. For systems with rear removal, a bar mat with corresponding cut-outs for the removal doors ensures fastening

Robust, weather-resistant materials are required for installation on the fence. KNOBLOCH uses here:

  • Stainless steel – durable, modern and rust-resistant
  • Aluminium – lightweight and corrosion-resistant
  • Powder-coated sheet steel – versatile in colour design and robust. KNOBLOCH uses a high-quality passivation (galvanisation) for sheet steel for reasons of corrosion resistance
  • Plastic – lightweight, corrosion-resistant and cost-effective, but less resilient than the other materials, both mechanically and to weathering. KNOBLOCH therefore uses plastic in mailbox systems almost exclusively for nameplates

Fence letterbox systems are actually always one-offs – if only because the drill and fixing holes have to fit the respective fence exactly. Nevertheless, the principle that the standardisation of compartments enables higher quantities and therefore a price advantage, which KNOBLOCH passes on to its customers, also applies here. The compartments can be customised to your personal requirements:

  • Size and orientation of the compartments
  • Number and arrangement of compartments
  • Colour of the compartments and colour of the flaps
  • Type of flaps (from simple to noise-damped to flat design)
  • Additional functions: Integration of bell systems and parcel lockers as well as functional boxes with (almost) any content, from door openers for wheelchair users to access controls
  • Design: Modern, classic or according to special architectural requirements

A mailbox is usually installed on a fence or gate as follows:

  • Positioning – determine the location on the fence where the letterbox should be easily accessible. The fence must have sufficient load-bearing capacity. For KNOBLOCH letterbox systems, a rule of thumb is a weight of 4 to 8 kg per letter compartment (depending on the compartment size).
  • Fastening system – the model variants with front removal are simply screwed directly onto the fence, the rear wall of the system should have corresponding drill holes.
  • Systems with rear removal are installed in a cut-out in the fence (which may need to be created), the dimensions of which should be clarified during the ordering process, as should the fixing material to be used.

KNOBLOCH always supplies letterbox systems with a link to detailed installation instructions, which can be conveniently accessed via QR code. However, from a certain size of system (guideline: if several people are needed for installation), it makes sense to have the installation carried out by specialists to ensure stability and safety.

KNOBLOCH itself offers an installation service – just ask us.

In principle, fence systems offer more points of attack than their wall-mounted counterparts, which are protected at the sides. However, the differences are not too great – at least with KNOBLOCH systems:

  • Robust locks protect against unauthorised access
  • Hard-wearing, strong materials make breaking open and vandalism more difficult
  • Weather protection: Special design details such as rain edges, seals and canopies protect the post from rain and snow

Of course, we can only speak for KNOBLOCH at this point – and here the answer is a resounding yes. This applies not only to the materials used:

  • Corrosion protection through stainless steel, anodised aluminium and galvanised, powder-coated sheet steel
  • UV resistance: we only use colours and surface treatments that will not fade over decades
  • Rain protection: special constructions such as rain edges together with seals prevent water from penetrating the compartments
  • Private properties – detached or terraced houses where the letterbox should be accessible directly from the street (and without having to ring the doorbell)
  • Residential complexes – larger apartment blocks with enclosed front gardens
  • Commercial properties – business premises or company buildings where a concierge is to be saved or relieved of some of the workload

The European standard/letterbox standard DIN EN 13724 specifies the requirements for size, weather protection and security. The key points:

  • Size of the insertion slots – so that magazines and large letters can also be delivered uncrumpled
  • Accessibility – also for people of small stature, possibly for wheelchair users
  • Protection against unauthorised access and vandalism

For KNOBLOCH fence letterbox systems, the necessary or sensible maintenance is limited to a few points:

  • Regular cleaning – with a soft cloth and mild detergent
  • Polishes – there are special care products for stainless steel and aluminium that can be used a few times a year
  • Function check – is recommended for locks and seals at longer intervals

The cost of fence mailbox systems depends on the material, size and features:

  • Small systems: From approx. 150-300 euros
  • Medium-sized systems: Between 500-1,500 euros
  • Large, customised systems: 2,000 euros and more

KNOBLOCH relies on a modular system with standardised letterbox compartments. This enables customised solutions for different budgets – always with high quality standards and a long service life.
