4 way T-joint + down horizontal. The DT22 series is a 2-point-trussing-system with conical coupler (spigot), trusspin and safety clip. The advantage of the quick connector system lies in the fact that it closes force-locking the belt tube and allows rapid assembly and dismantling. The four tubes are made of 35mm aluminum 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. The system also includes cones, 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, base plates and much more solutions will complete the product range. The system is from European production which is compatible to the most common systems in the market and is TÜV approved.
