Earth Clamp EC14 Internal A-D 12-32mm Pack of 20 is rated 4.2 out of 5 by 19.
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 5 out of 5 by from Earth Clamps Great item, easy to use and good bonding achieved. When tested there were no issues at all.

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.

Rated 4 out of 5 by from Bonding Strap A good product and does what it says on the pack. The price was good and in stock.

Rated 2 out of 5 by from false economy These are fine for single connections or if you use lugs and a crimper, but the bolts are small and a little short, so two 10mm cables without lugs, used under a boiler for example, are quite hard to secure. Design wise, if the bolts on this one were longer/bigger it wouldn't help, because of their position in relation to the pipe (the bolt would be too close and damage the pipe). Some competitors products are better in my opinion. If I was using these regularly, I would buy something else.

Rated 5 out of 5 by from Easy to make good connection Easy to attach and get a good connection to the pipe. Good size terminal for connection bonding cable to - although best use with a ring crimp on the wire.
