CUSTOMER REVIEWS

Rated 4.3 out of 5 by 3 reviewers.
Rated 3 out of 5 by My Bad, Trade Size, Who Knew? Yesterday I submitted a negative review about this product. Then it came to me after waking from a good sleep. THE DARN LABLING INDICATED "TRADE SIZE". I had found an old, but unused light fixture with 1/2" knockouts. These were 'real world' measurements, with 1/2" measuring 1/2" true. I've been doing electrical wiring for 60+ years, but not as an 'electrician'. I've always been on the smart side of the electrical world, . . ELECTRONICS and Communications. I didn't know that electricians had stupid secrets for craft protection. Sorry about the negative review. Ray November 9, 2014
Rated 5 out of 5 by Excellent, easier to retrofit later These are excellent clamps. I'm in the process of retrofitting a house that has old metal boxes and 2 piece clamp connectors. The advantage with these is that you can loosen the wire from within the box, while 2 piece clamps can only be removed from outside... That means I have to destroy the box, the wire, or open the wall to get the clamps out. If these clamps were in the box, I could have removed the ring, extracted the box and save both the wire and box. I strongly recommend these to anyone using metal boxes. I would note the they have contractor 100 packs in store sometimes, but I haven't seen them online. Big cost savings in bulk as you can imagine. Otherwise this 5-pack is a better deal than individual at least. November 26, 2013
Rated 5 out of 5 by Excellent Clamps! These work great, for new work and for retrofitting. Attach easily to junction boxes and screw on tight. they keep romex cable very tight and secure. I would recommend anyone needing to run romex into junction boxes. March 25, 2014
