ABSTRACT:
The joint is formed between two mutually perpendicular tubes by seating a washer in one tube, a nut within the other tube and by passing a bolt through the washer into threaded engagement with the nut. The resulting joint is hidden from view. A spreader bar is formed by joining the ends of two tubular sections within each other after each section is joined to a tube.
