Used roll of Structure Cable
Contains: (2) Cat 5E + (2) RG6/U Quad Shield + (2) FDDI/Fiber
From what I understand they come in 500FT spools, it looks a little under half way on spool from pictures.
End is at # 002444FT mark and increasing to 002446FT in picture so there is at least 56 FT or possibly more on the roll?
