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 two tubes are made of 35mm aluminum tube with a wall thickness of 2 mm 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.
