Clow Class 1 Aluminium Trestles are constructed from aluminium box section stiles and cross bars.
Each trestle is hinged at the top with galvanised steel hinges to prevent over splaying - additionally strong rope ties are also fitted as an added precaution to prevent over stretching.
The image here shows the Clow Aluminium Trestles complete with a Clow Aluminium Staging Board.
