There are two types of platforms: triangular, adapted to the opening in the square and round ceiling, and trapezoidal, for the square hole. The model of stairs has both left and right treatment, that's why many assembly concepts are possible due to the universal form of these stairs.
The stairs are adjusted only after the ordering of the height at which the platform is to be located - flush with the floor on the upper ceiling. Non-standard orders are possible to implement in consultation with the manufacturer, after sending the appropriate projections of the room where the stairs are to be located.
