Solar Fixing Systems

With both environmental and technological resources under increasing pressure, the pursuit of sustainable sources of renewable energy have become a decisive aspect of everyday life in both households and industry alike. Worldwide, a fundamental reorientation in energy provision is currently underway – and PV (photo voltaic) systems represent the base technology for this reorientation.

The perfect symbiosis...made possible with the new RTP S5 Clamp

Precisely because of its constructional design, the Craft-Lock® roof profile offer an optimal basis for the installation of PV systems. The modules can be attached to the profile panels by means of specially developed RTP S5 Mini clamp. As a result, no holes are drilled in the material and thus no drilling chips are left behind on the roof shell which would accelerate corrosion and cause leaks – a significant advantage over most normal roof profiles.

PV in Connection With Reehfalz

The Perfect Symbiosis With The New Reehfalz S5-Clamp

S5 clamp with PV kit for direct attachment

In the case of PV attachments with the innovative S5 clamp, the PV modules are laid down directly on the module breaker plate and attached with the module clamp. An extremely rational instalment is thus made possible.


A floating module installation system with short rails and S5 clamp is currently under development, in which an absolutely flexible module arrangement will be possible on every roof and any possible type of expansion of length can be incorporated.

Rail attachment

With this rail attachment, complete independence with regard to the design and dimensions of the PV module is attained. On this basis, even complete coverage of the roof surface can be considered.

The Perfect Symbiosis with the New RTP S5-mini-Clamp

RTP S5-Mini-clamps for direct attachment

In the case of PV attachments with the innovative S5 clamp, the PV module is directly attached to the clamp. An extremely rational installation is thus made possible. Adding to this concept, it is furthermore possible to attach a rail system to the RTP S5-Mini-clamp with the aid of an adapter. A floating module installation system will also be available for the S5-Mini-clamp.

Just In Time Production

Planning and precision – no delays to your project

On the basis of the close collaboration with our partners in the domain of PV system construction and the outstanding suitability of our profiles, we can guarantee both optimal planning and prompt mounting of the systems – the perfect solution for our customers.

The final work on the roof (in this case the roof capping) can often be carried out at the same time as the start of an installation of the PV system and in parallel.

Holding Force of the S5 and RTP Mini-Clamp

The holding force of the S5 and RTP mini-clamp has been tested on the Craft-Lock® original profile. This has reaffirmed that the clamp has a holding force which is unrivalled on the market. In order to convey maximal force, it is necessary to tighten the patented grub screw with a torque of 17 Nm.

Depending on the type of application, it must be ensured that the forces acting on the clamp are diverted into the supporting and/or base structures.

When planning metal roofs, not only the load from wind and snow, but also the use to which it being put at the time must be taken into consideration. Instead, reserves able to absorb greater loads stemming from a later or an expanded use of the roof, such as photo voltaics, for example, should be planned for.

When in doubt, a stress analyst should be called in to determine the load and how it is to be absorbed.
