This rattlesnake cord was perfect for my old WE Candlestick phone. It would be nice to have some guidance for tying off the jacket on those old phones. (I realize now that I accidentally mentioned this strain-relief comment on the 5-conductor cord, which has no extra cloth to tie it off. My apologies.) Regardless, the product quality is solid. So, nice to get rid of the previous cord, which was disintegrating.
