Thanks for posting. I bought the adapter and then it was off to Home Depot for PVC hardware. I am using a speaker stand, so I bought a 1/2" x 3/4" reducing male adapter, a 3/4" coupling, and 3/4 inch pipe. The PVC adapter and coupling fits in the tube of the speaker stand. The pipe is used as a spacer. The "nut" on the PVC adapter prevents the assembly going completely into the tube. I am going to drill a hole through the coupling that lines up with existing holes in the tube and put a bolt through to hold it.
