This speaker connector is supplied in two different versions with the same description. The panel has on the front and back of each hole for banana plugs with lateral hole for direct connection of cables with the help of the rotating ring. One version has an up to back-stop from the front hole and thus takes the banana plugs on fully. The second version consists of a two-part connector with isolation (no continuity) in the middle. This go here the banana plugs only halfway in, I do not like.
Unfortunately, one does not know before what you get.
