Best Ground Clamp
Best ground clamp I’ve used. Absolutely no resistance to ground after removing old clamp, cleaning the pipe ground and wiring with Deoxit and a metal wire brush. Very highly recommended!

Never would have thought of the double ground wire clamps. But it does make for a more secure grounding system. Grand idea !
