These were recommended to me and so I bought some for my 12 gauge speaker wire. They are the screw set type. Can someone tell me how to use them? Do I put the speaker wire in, pull it partway out through one of the holes at the top of it, and then put that little metal pellet type thing back in and screw the bottom back on? Here is a link to the type I got: http://www.partsexpress.com/pe/pshow...091-1165&Did=7 If anyone can help that would be great. It doesn't show the holes on either side that are at the top in the picture though.
