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

Mounting solutions for pitched roofs

SingleRail

SingleRail

  • Quick and low-cost with direct lateral connections to the rail without additional components including customised height adjustment
  • Secure snap-in assembly - without needing to be screwed into the base plate
  • The SingleRail in combination with CrossHook roof hooks is very durable and versatile
