[TowerTalk] methods of using conduit in the ground for cables

[John Carolyn Watton]

Since we are talking ground cables . . . I happen to have at least 33 new, still in the package:

Andrew Sureground LDF5 Grounding Kits

2 hole field attached lug

Type SGL5-15B4



Any interest?  I'm thrilled to sell them quite reduced.



Thank you,

JQ
