Belden #20 PTFE Teflon ins wire, stranded, silver plated copper 100 ft roll NOS 100% New and Unused. The dash numbers form the complete Belden part number, so if you look up the Black roll, its number would be 83027-010. I love this stuff, and use PTFE Teflon wire for all my projects. byJuly 3, 2026
