[TowerTalk] Ground Clamps

[Roy & Peggy Bonvillian]

I have just set my base for my 55G and have my UFER ground wires that need 
to be connected to the legs of the tower. I have 3 #4 gauge wire coming out 
of the cement near each leg. My question is where do I fine the proper 
clamps to connect the bare copper wire to the 3 legs and also have a place 
to tie in the wire leaving each leg going out to the ground rods?
