The Pipe to Coupler Adapter can be used to rig pipe-mounted plasma screens, projectors and speakers from overhead pipe or truss. 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.
