The PUK-STRUT mounting system consists of mounting channels, bracket supports, brackets and head plates. The mounting channels are perforated profiles C+ with slots 22 mm wide. The brackets can be mounted on the channels and continuously adjusted so they can be set at any height. The KA 30 arms are suitable for suspending mesh cable trays and cable trays up to 400 mm wide. The KA 41 brackets are also designed for cable ladders and trays up to 600 mm wide. The PUK-STRUT mounting system has versatile possible uses and is suitable for most areas of application..

Airport Frankfurt
With almost 60 million passengers (2023), Frankfurt Airport is Germany's largest and Europe's sixth largest airport. In 2026, passenger numbers, which have fallen due to the pandemic, are expected to return to pre-crisis levels (~70.5 million) and continue to grow from then on.

Extension of the subway line U5
For decades, the current U5 subway line connected the eastern city center with the east and northeast of Berlin. Plans to extend the line to the west date back to the 1970s, but it was only with the reunification of Germany that these could be realized.

EDGE East Side Tower
The Berlin skyline is growing and another building was added in November 2023. With the 142 m high EDGE East Side Tower Berlin near ‘Warschauer Brücke’, one of Berlin's tallest buildings was built in just under 4 years. Particularly striking: the staircase-like curtain wall with almost complete glazing.

City S-Bahn S21 at Berlin Central Station
Berlin's main railway station is to be better connected to public transport. This is the goal of the construction of the new S-Bahn line S21, the so-called City S-Bahn. This line, which runs from north to south, connects the northern stations Wedding and Westhafen directly with the Central Station.
