Overall the clamps were easy to install and appear able to stand up to the NW BC weather conditions of rain ice wind and snow.Again, I was expecting a somewhat heavier clamp but all is well and I'm happy.

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

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.

Just what I wanted to ground a solar panel array and did not want to spend a ton on it.Great price and it will get the job done.After installing it on my grounding rod, I will spray it with a good quality rust proofing spray to prevent rusting from the elements.

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.

Nice heavy bronze not cheap zinc. I would never consider using a zinc ground clamp which can be deformed during installation.
