Stairs are composed of individual stair modules to match the height of the stage. The last stage is the step from the highest module onto the stage surface.
Each module, as well as the staircase combined from it, stands by itself and we therefore only attach to the stage surface and secured against slipping.
For this purpose, a toggle screw is set through the uprights of the handrail, which is screwed to a counterpart in the external groove of the platform frame.
If no handrail is used, there are separate connectors (see No. 4 in the picture)
