Speaker binding posts with plastic covers


My Krell amplifier has speaker binding posts with the clear plastic covers. Apparently these are for EU safety requirements. I want to use spade connectors and have no idea how to open these covers. I’ve wrestled with them but they don’t budge. I don’t even know whether they unscrew or pull out or whether there is some other method at play. Does anyone have experience with these?

BTW, if the top won't unscrew, maybe it's completely unscrewed! Try going clockwise and see if the top turns.

yes, you show a type, like mine and most, that does unscrew, and perhaps all the way out is a possibility, that would be the definition of dumb luck.

The link OP posted,

 

perhaps he just thought they all looked/worked the same, so he just posted that one, it just happened to be the rare one that does not unscrew.

IF this goes on any longer, we will need a photo I think.

The channel-lock pliers have set the binding posts free, hallelujah hallelujah! Thanks, guys!
