Worked Great
It worked exactly as expected. I used it to tie my incoming cable service to the house's ground bar.It installed easily to the ground bar and looks like it'll hold up. I'd buy again.

Fantastic Ground
This is all metal grounding, it’s very durable and is made to attach itself to grounding rod! The size is perfect and you can attach 2 wires to it easily.

Nice
If you don't know what this item is, then you don't need it. If you do know what it is, then rest assured that it is very durable and will outlast most human beings. Also, I was able to use mine with number six solid wire.

Good Ground Clamp
We had some plumbing repair and the plumber replaced some of the copper pipe with PEX. The electrical panel was located on the opposite side of the house from the water main and the panel was grounded both to a ground rod outside but also to a water line. An electrician said it wasn't really necessary to ground it to the water line in this case, but if we wanted to be extra safe, we would put a ground between the copper on both sides of the new PEX. We bought two of these and grounding wire and easily installed these. They are high quality and easy to use. They were also significantly better priced than our big box hardware store.
