Every stage requires stability. This can be ensured on legs up to a height of approx. 60cm. At a height of 80cm and above, the stage must be "winded", i.e. diagonal struts must be used to ensure that it is reinforced and remains resistant to movement, which may be generated by, for example, folklore groups or other sources of movement. Weathering is a requirement for taller stages or larger stages in general. It is also recommended for uneven terrain where 100% stability of the substrate is not guaranteed. To compensate for unevenness, you can use the dilettante screws of the levelling screws or the helixes of the so-called spindle spindle, but it is not only about stability from top to bottom, but also horizontal movement.
