SIGMA ENGINEERED SOLUTIONS ProConnex 41309 Ground Clamp 1/2" - 1"

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.

These clamps worked perfect on my 3/4 copper supply line to my house. Used to tie all grounds together.

Work great!

We used this to in our grounding system for our antenna. Husband installed, had no issues and in a matter of minutes. Good quality.

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.

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.

I've been using these grounding clamps for a while. They really come in handy when you need to ground stuff like a generator or the electronic circuit in your home. I had some serious blow outs and a lightening bolt one time. Grounding your system really is a life, time and money saver. If you're not properly grounded, you could lose all your home electronics and the grid system. These clamps will keep your electronic apparatus happy and running.. . even your washer.

The product is high quality. It meets the Electrical Code requirements for grounding
