The Pipe to Coupler Adapter can be used to rig pipe-mounted plasma screens, projectors and speakers from overhead pipe or truss. Special versions are available with cable holes through the side to run power and signal cables inside the vertical pipe. The Pipe to Coupler Adapter attaches a standard threaded NPT 1-1/2″ pipe (1.9″ OD) to a Mega-Coupler. There are two interlocking tabs to keep the adapter from rotating. The Adapter is fastened to the Mega-Coupler with a 1/2″-13 tpi by 1″ long bolt and a jam nut (not included). There is a 1/4-20 set screw to lock the pipe rotation, and an inspection hole to verify that the pipe is fully inserted.
