Which country is this product manufactured in please? Does it say anywhere on it? Thanks.

Unsure whether this item is a single or pair of clamps?

According to the items technical details it appears to be just one clamp. When i purchased mine, it was a pair for just a little more than the price here. If you require two, then select 'Twin Pack' from the options.

Easy to apply pressure and just as easy to release

As I get older (now over 70) I find it difficult to tighten things up as strongly as i used to and need all the help I can get. This Irwin Quick-Grip really works for me. Very easy to bring the jaws together and apply lots of pressure and just as easy to release after use. Well made so should last a long time. I only purchased one just in case I did not like it but will buy another to make a pair.

Great clamps

Splendid clamps, easy to use and very good clamping force. The only criticism is the rubber pads tend to fall off.

Yes for heavy duty.

1st class, heavy duty clamping set. Delivered quickly. Feel very robust, but not for small hands. Good value for quality.
