Answer: 
No, this item features a steel screw that will corrode if exposed to the moisture in concrete. We recommend our model JD-B1-15. This model offers a bronze screw and is rated for direct burial including concrete.

Answer: 
These are available on-line but are available only in full case quantity (internet sku 202921021). Since you only need 2, it seems to make more sense to purchase in store.

Rated 3.8 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Easy to install The old ground wire was too thin, so I replaced the thin speaker wire with some 8 gauge wire. I hooked up the new wire to this ground clamp. It was very easy to install and fit perfectly on 3/4 inch copper tube. The screws work with a slotted, Phillips or square screwdriver. Now my house is properly grounded and has a very safe electrical system! May 2, 2015
Rated 4.0 out of 5.0 by Does what it is supposed to Works well when used to clamp ground wire to 1/2" to 1" underground water pipe. NOT designed for use on 1/2"ground rod as in previous post. 1/2" copper pipe is 5/8 OD and works fine. Screws rust minus 1star. January 7, 2014
Rated 5.0 out of 5.0 by how to install you have to turn the one side around to make it fit on smaller sizes its best to use a licensed electrician in you are worried about electrical safety November 19, 2013
Rated 1.0 out of 5.0 by doesn't work for 1/2" ground rod although the description says 1/2 to 1", it just barely stays on my 1/2" ground rod. in fact, even fully tightened, i can wiggle it off the ground rod. That's not tight enough when my safety is dependent upon a solid connection to ground. May 4, 2013
