Hercules - One of the best and most stable rafter brackets on the market.
For your safety. Make no compromises and get the best for your customer.

Thanks to the latest technology, this rafter bracket has a 100% - 400% larger contact pressure area than comparable brackets. This drastically increases the friction force. In addition, more than 2000 teeth engage in the cone of the mast and thus ensure a firm hold that does not change its position even during storms. However, the mast can still be released and repositioned.

Max. Bending moment 1000Nm (thus holds almost twice as much as comparable rafter brackets)
Security is important to us. That is why our holder is delivered with a safety nut that does not come loose even under constant load on the roof.
This development was designed to be extremely easy to assemble. Ultra-fast child's play
Assembly. With the exception of 1 screw, this holder is completely pre-assembled.
Thanks to the double sliding technique, the mast can be moved and adjusted to the desired position.
position has become even easier.
A maximum contact force is generated by the given angle of the 2 cones.
Thanks to the narrow cone on the mast, the holder is ideally suited for all roof coverings supplied on the market.
Continuously adjustable roof pitch
No cold bridges in the house roof
No damage to the roof cladding
The mast is hot-dip galvanized and therefore offers the best protection against weather and environmental influences.

rafter

The rafters are the wooden parts that extend from the eaves to the ridge and meet there. Together with the roof purlins, they play an important role in roof statics. The rafters carry most of the load of the roof. This means that the roof windows are installed between the rafters.
The rafters are almost always so strong that an overarching rafter bracket can be installed without any problems and without affecting the statics.
Common cross-sections of rafters in single-family houses are often 8/18 cm, 8/20 cm etc. thick. The thickness of the rafters varies depending on the structural design and thermal insulation.
Since thermal insulation and, more recently, on-roof insulation are always used between the rafter brackets, there is also a lot to consider here.
Avoid thermal bridges at all costs!!

When using a Herkules rafter bracket there are no thermal bridges!
No damage to the roof cladding, as installation is carried out from the outside.
What causes thermal bridges?

Constructive thermal bridges exist when materials with high thermal conductivity (an antenna tube) penetrate an external component with better thermal insulation. Examples of this are:

Previously used antennas Tubes
An insufficiently insulated window lintel
A cantilevered reinforced concrete slab (balcony)
A reinforced concrete ceiling support
The interference zone of a thermal bridge (area of temperature reduction) also extends into the surrounding component.
Thermal bridges can also be caused by improper design:

e.g. gaps in the insulation
The low internal surface temperature in the area of a thermal bridge can lead to condensation. Dew water forms when warm, moist air hits a cold surface and is cooled below the so-called dew point. The humid spots then occur permanently and it is

It can be adapted to the shape of the tile like no other material and does not lose its shape in the cold or heat.

With a diameter of 48mm it fits perfectly to the rafter tube. In addition, however, Coroplast adhesive tape, e.g. the connection between pipe and sleeve, must be wrapped around again.
This has the advantage that even with
