What is the thingie on the WBT Bananna Plug

I am looking at getting some bananna plugs, and in particular have noticed the WBT model 0645. It looks like it has an insulator or something plastic that protrudes from the front parallel to the bananna extrusion. Anyone know what this is? Looks like this will prevent the bananna portion from going into the receptacle, will it?

Also, any comments on this plug, where to get it, or other comparable connectors. Please, Bananna only because that is all my speakers will take, the have 4 bananna holes per speaker (no "spades are better" please because I can't use them).
Here is the wbt cite

Thanks in advance for your helpful comments and/or jokes!

I think I understand your predicament. In my case the binding posts/knobs add distance so that the plastic plug never bottoms out against the cabinet. Are you saying because you only have flush holes, that the plastic plugs may prevent you from inserting the banana securely into the hole? If I'm correct, I don't think the angled WBTs will work for you. I just took a look at my WBTs, and it seems that the plastic plug does not protrude as much as the banana plug. But, there is only about at most a 1/16" difference, which may not work in your application.

Have you looked into the other WBT bananas? They don't use the plastic extender plug that the angled ones do. The Analysis Plus Oval Nines I used to own had the Midlines with plastic twist sleeves. The WBT Topline bananas I believe uses a metal twist sleeve. Although the angled WBT sleeves are plastic, I feel they are much easier at locking then the Midlines. I have no experience with the Toplines though.

Let me know if I've accurately described your situation.

Are you referring to the angled WBT bananas? I believe I have what you're referring to on my biwired Virtual Dynamics speaker cables. The protruding plastic pins seem to help with alignment and in my case, keep them right side up and prevent them from twisting during tightning. They actually fit snuggly on the other side of the banana plug and don't seem to hinder installation. If they are there for another use, I haven't figured it out and I'm using them incorrectly. Good luck.
