I have a few more of these left but not many. Very tiny glass spool that is a lot smaller than any spool I have seen before. I suspect that these were used for indoor, low voltage use on uninsulated wiring. The WG is so very small that most any sheathed wiring would not fit.VVNM condition. This is the smaller, narrower version. I have sat it next to an electric fence insulator for size comp. First mail to me... $12 + actual shipping FCM.
