This item allows the installer to create angles of 90 degrees when working with 32mm tubing. It can be used on horizontal ramps and similar fixed rails where the need to create a realigning angle is required. It is not meant to be used in a vertical bending aspect. It’s a two piece design that has three tightening points. With the rail positioned on the knurled section, securing the rail is achieved by tightening each half. Each half works independently to expand the split piece wedge. The allen key design in the centre is used to tighten the joint at the selected angle.
