I bought these flex pin plugs to connect a center channel speak that did not have the usual posts. Installing these was simple and quick. They work great and I'm glad that I have extras lying around for my next project.
Please note: If you're buying these to use with the pre-terminated Sewell Direct deadbolt banana plug cables, they are not interchangeable. That is to say, if you have the pre-terminated cables you cannot simply unscrew the banana plug and replace it with the flex pen connector. Bummer, I know. Those cables and these ends would be a 5+ star product if they were interchangeable--as they should be.
