Special adjsutable version of the modular U-Frame truss segment for light and other equipment suspension. Depending on size of the gear, you can adjust the size of the U- Frame inner dimension by moving the cross bar up and down and securing it in the pre-drilled holes by safety pins. The safety pins both in connectors and for cross bar positioning are inserted into the tubes from front of the frame. The aluminum tubes used are 50 x 3  mm (2 x 0.12 inch) for higher level of strength and loading capacity. U-Frames can be interconnected into one line or various shapes introducing new design possibilities for creative designers and show producers. The U-Frames help to create hanging points or rigging points at tight spots where standard truss or bulk supports cannot be used. Standard quick-lock connection makes it possible to use FT31 pipes with the U-Frames, however, any type of connection is available on request.
