Good bonding bridge
Good value for the cost easy install my township electrical inspector is requiring 2 ground rods and a bridge on every house to get a CO my local hardware store was sold out but amazon came to the rescue the only thing is just a heads up does not come with mounting hardware not a deal breaker but if you are on the job bring screws to mount it

It will do
It works, no complaints, and the price isn't bad. Just do not over tighten the #3 screw that you run your panel ground to. It will break every time. I did it, then the guy working for me did it. But then I got on Amazon right away, ordered more and we were back in business right before the inspector came.

Great product
Great price for a product needed on every new house I wire. Meets code and much cheaper than Arlington

A high quality bonding device
The Sigma 42400 is a high quality bonding bridge that is easy to mount and is useful for bonding grounding electrode conductors, phone and internet cabling, etc. It is relatively inexpensive, and I would recommend it to anyone who needs to ground these systems at one convenient location, either outside or inside a residence.

I liked it too much
It's a perfect bounding clamp.
P**.
If you need to bond different parts together to a common ground, this does the job. Far less expensive than the alternatives.
