Rated 5 out of 5 by from Earth clamp This clamp was ok for the job I had, however I understand the complaints when using multiple connections.

Rated 3 out of 5 by from A bit tight It would be so nice if manufacturers, actually thought about the installer. 10mm cable to one service to another, Best practise is to loop the cable around the terminal screw, with no cut in the cable. So why don't they allow this to be done with ease. Screw needs to be slightly longer.

Rated 5 out of 5 by from Bonding galore Needed to upgrade the bonding on an old system for an EICR and these did the job.

Rated 1 out of 5 by from Not For Me I didn't like these at all and wouldn't use them again. I only bought them because I had ran out of the brand that I normally use and needed some earthing clamps in a hurry. Like several other reviewers, I wasn't happy with the final connection to a 10mm cable. Three of the clamps fell apart and had to be discarded. My advice is not to use this brand and instead, spend a little more and buy the Tenby brand which are far superior.

Rated 2 out of 5 by from Not recommended The washers under the terminal screw on these clamps is so thin that they bend on tightening. Do not buy this Greenbook product.

Rated 5 out of 5 by from Good value Good positive fit on the three pipes sizes I needed (15, 22, and 28mm). Slightly cheaper elsewhere but not by the time the delivery is paid to Aberdeenshire. Agree they are better with the ring crimp on the cable.
