K2 Systems GmbH
The German company based near Stuttgart develops and produces mounting systems for solar pv installations. For the most part, the products are made from high-grade steel and aluminium, offering the right choice for the demands of any location – whether you choose an off-the-shelf or customized solution.

The K2 Principle
The M K2 slot nut is found in all K2 mounting systems as a central connecting element of various applications in the mounting rails.
Benefits for you
- Easy insertion from the top in all the K2 mounting rails
- After being inserted and turned, the M K2 slot nut locks itself in position (preventing it from sliding when the rail is installed on an incline)
- The M K2 can be pushed by light pressure into the rail precisely to the exact millimetre
- Cost-effective thanks to optimal use of material
