These are brand new banana plugs from Dayton. Bought them off E-bay but they are sold at PE. They won't fit anything I have. PE part number 091-332. I paid $3.50 each and have 6. These are gold plated and I have 3 red and 3 black. Will sell all 6 for $20 shipped. I have a picture and they have not been opened-except one box where I determined it won't fit my need.
