I’ve been using binding posts, banana jacks/plugs since childhood. Rumor has it that they have been around since 1924. They come in a few different styles but they all pretty much do hte same thing. The caveat is that the ones that I like to use all have “flattened sides.”

This means that if you want to use them without their rotating in the panel, you need to drill a hole and then do a lot of filing. “Double-D” punches either do not exist, or the salespeople at Digi-Key, Newark, McMaster-Carr, and a few other places, don’t know their stuff.
I was fortunate to be able to use a laser to cut out a faceplate with double-d geometries, and indicator lights, and a hole pattern for mounting on to a standard 1900 (4″ square) electrical box. Send me a note if you would like the illustrator file.
