Abstract: Disclosed is a canopy support arm assembly formed from a support tube having a continuous sidewall that can be cut to size at a job site. The support tube is coupled on each end by base elements having a receiver end sized for receipt of the end of the support tube and a conical shaped barrel having threads formed along an outer surface. An aperture passes through each threaded end for receipt of a threaded rod that is constructed and arranged to extend through the threaded ends and aperture using nut fasteners to provide a compression force between the elements. A first connector having a threaded receptacle engages the threaded end of the first base element, concealing one of the nut fasteners. A second connector having a threaded receptacle engages the threaded end of the second base element, concealing the other nut fastener.
