The 
Трубы для сценографии with a round section are used to make the 
Верхние рейки and the 
Балластные трубы.
The 
Верхние рейки are bars for hanging light loads, such as borders, wings, light backdrops and screens.
They can be secured to the bearing structures with various accessories, including the 
8C50 - Зажиm Ø 50 mm + гайка M8.
If movable to be lifted by 
Ручные подъемные системы, they are supported by textile 
ropes usually tied with 
clove hitches.
The distance between the fixing points depends on the load and does not exceed 3 m.
Верхние рейки  of various lengths can be made by joining the segments with their connectors, normally without exceeding 12 m, in which case they require at least 5 suspension points.
The 
Трубы для сценографии are also used for the 
Балластные трубы to be inserted in the bottom pocket of backdrops and screens, these too to be joined with connectors, with no length limits because they are supported by the backdrops themselves.
Upon request, the 
Трубы для сценографии can be curved and enamelled.
