With an SWL of 750kg, and constructed from high-tensile aluminium extrusion, these clamps connect two tubes, diameter 48-51mm, at an angle, with minimum spacing or “drop”. The greater contact area of the extrusion results in less damage than typical pressed-steel types, to give great strength, with less weight. Three types are available, each constructed of two connected assemblies. Swivel versions rotate about the joining bolt whilst parallel couplers and 90% couplers connect two pipes at a fixed angle.,
