DT 22-200 The DT22/2 series is a 2-point-trussing-system with conical coupler (spigot), trusspin and safety clip. This quick connector system closes force-lockingly with the belt tube and allows rapid construction during frequent assembly and dismantling. The main tubes are made of 35mm aluminium tube with a wall thickness of 2mm and give this system an outstanding strength-to-weight ratio. The struts have a diameter of 8 mm. Each truss length includes all necessary conical connectors, steel pins and safety clips. Optionally the system can be extended with various lengths, corners, T-branches and angles. Extensive accessories such as hooks, connectors, floor plates, wall brackets, spacers and much more complete the product line. The system is from European production which is compatible to the most common systems in the market and is TÜV approved.
