Review: Super grip! - Ok, so these are quite pricey compared to others available. BUT, these are the only ones that I have purchased that have done ALL I asked of them and are still in one piece. The grip is SERIOUSLY strong. It was able to 'persuade' things to move in to position that I was less able to do with hands alone. It is also really handy to be able to switch the head so that you can push things apart, or lift them off the ground like a hand held mini jack! Another big plus, that I have yet to find on other brands of this product, is that the clamp head can pivot, meaning that clamping awkward shaped items is MUCH easier. Don't hesitate, if you have come to this product page and are looking for a quality product, look no further. HOWEVER, DO consider buying the larger opening clamps, 12", 18" or even 24" if the work you are going to be doing is not going to be in a confined space. The larger ones are exactly the same quality but will cover you for a wider range of tasks. Unless you are working with restricted spaces, for which these are perfect1

## Questions & Answers

**Q: Do the irwin decking clamps fit this**
A: Yes

**Q: Will these work to hold 3 scaffold boards together during glueing?**
A: The 18 inch quick grip will exert sufficient force to glue the boards together, but I would be reluctant to to rely on glue alone. It depends on what you intend to use them for. Also you have to make sure the edges or faces to be glued are clean, smooth and flat. If you are glueing edges they must be square to the faces or you will end up with either an uneven surface or if you hold the faces flat you will have a weaker edge joint as the edges will not meet fully. Depending on use, why not dowel edges, clamp together with a good bead of wood filler along the edges and this will fill any gaps with the surface being reasonably flat. Rub down wood filler with fine emery paper and finish as you want. I hope this helps.

**Q: Is the 600mm clamp actually 600mm as the Product Dimensions show 30.48 x 5.08 x 12.7 cm; and the item dimensions are 30.5 x 5.1 x 12.7 centimetres**
A: If it helps I have the 300mm clamp. The distance, between jaws, at maximum extension is 305mm. This seems suspiciouslke the 304.8 you are quoting. So looks like a mix up between the 300 and 600mm clamp.
 So I would assume the 600mm will be at least 605mm between the jaws at max.

**Q: Hi Guys, so can the 18" be connected together for a wider range - so x2 18" would give and overall 36" range - is that correct please?**
A: Don't see how you could tighten them by doing this, plus you can only get a maximum range of 30" if you could.

### ⭐⭐⭐⭐⭐ Quality
*by C***R on 18 February 2025*

Quality clamps with consistent clamping power. Worth the extra cost over cheaper versions.

### ⭐⭐⭐⭐⭐ Quality comes at a price
*by A***E on 2 January 2014*

These Quick-Grip 5062Qc Twin Pack Bar Clamps seem to be a bit too expensive at first glance, yet one has to consider two points: 1 It is a twin pack 2 Top notch build quality. I have bought many cheaper clamps in the past, yet all ended up in some drawer never to be used again due to numerous factors... Poor build quality, very small jaw width .... These Quick-Grip 5062Qc Twin Pack Bar Clamps are definitely keepers. They are made of durable heavy duty materials, and are extremely versatile. I have bought 2 of these, so in total I have 4, meaning that I am covered for most jobs requiring clamps. You never seem to have enough!! Do not waste your money on cheap alternatives. If you really want quality, than this is the way to go. Highly recommended.
