K2 mounting systems for trapezoidal sheet roofs without fixing the substructure are fixed with self-tapping sheet metal screws in the high beading. The SpeedRail system is the classic choice, which is suitable for nearly all situations. In some cases, the MiniRail and MultiRail systems may be suitable.

Elevated systems are possible using D-Dome and S-Dome, since they are mounted on SpeedRail mounting rails. Otherwise, elevated systems can be created by combining the MultiRail system with the S-Dome Small system. Otherwise, Triangle or MultiAngle systems can also be installed on trapezoidal sheet metal This allows for flexible elevation angles from 10 - 45°.

For Klip-Lok and Klip-Tite sheet metal roofings we offer the RibClamp KL system.
