The curved bar is 1,770 mm long and 410 mm high. It is easy to use thanks to its width, and it is also suitable for children to jump and balance on. The frame is made of a hot-dip galvanised steel tube measuring 60 mm in diameter. The ball joints and panel fastenings of the frame are made of glass-fibre reinforced polyamide plastic for outdoor use. They are highly durable against temperature and weather changes and physical impacts.
