The FixStop 2.0 ensures reliable fixation, for example in the InsertionRail 2.0 system (facade or pitched roof) on the CrossConnector 2.0, as well as in the BasicRail system (Landscape) with the AddOn XS, to prevent the rails from sliding out. The FixStop 2.0 is supplied pre-assembled with an M8x8 hexagon socket set screw for quick and easy installation.
