The 120 Degree Bracket is perfect for connecting two channel pieces at 120 degrees from each other. Each side is 48mm wide to fit perfectly on the channel. Use three brackets with 3 channel pieces to make 3 wheeled robots. As with the other Studica Robotics building components, it has the common hole pattern which makes it easy to connect to other structure with very little or no additional machining required. You can easily connect to other channel, extrusions, bushings, bearing, mounting brackets and more so you can quickly assemble and disassemble robots and automated systems.
