The 0‑line is marked by a white line, 0.01m wide which extends beyond the outside edges of the uprights.The two uprights must be installed on horizontal bases, level with the 0‑line, such that each can be moved from the 0‑line not less than 0.80m towards the landing area (eg on a built‑in double rail) or in fixed sockets with movable cross bar supports.
In the case of a runway with a permanent surface, this requires a built‑in installation tray made of corrosion protected metal in which the take‑off board is correctly positioned.
During sport free periods, the take‑off board can be removed.
When located outside the track, it is usually constructed as a symmetrical facility with one landing area in the middle of two runways.
When located within a segment, it is usually constructed with two parallel runways with positions for landing areas at each end.
The runway is a minimum of 40m long and is measured from beginning of the runway to the 0‑line. It is marked by white lines 0.05m wide or broken lines 0.05m wide with a length of 0.1m and a distance of 0.5m.
