K2 Systems GmbH
The German company based in Renningen (near Stuttgart) develops and produces mounting systems for 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 to insert in all K2 mounting rails
- M K2 are easy to lock following insertion. This prevents the rails from sliding down when positioned on a slant.
- M K2 can be pushed into the rail precisely down to the exact millimetre
- High tensile force
- Material: Stainless steel (1.4301) / TPC
- Thread : M8
- Cost-effective thanks to optimal use of material
