wolfcraft 2 Quick Clamps I 6176000 I for Quickly Fastening workpieces on All Tables with 20 mm Holes

These clamps are certainly of a simple design and are made of strong stuff! Having used them to hold some wood in place on my mft top, the clamps were easy to position, both for height and for direction. The clamping force was excellent and the turn required to provide this force was only slight meaning it could be achieved with one hand (just). Others have commented that the clamps can leave marks on the surface of the material being clamped and I would agree with this, but they do not leave any mark greater than any other clamp I have used at this strength. You can easily mitigate this by using some shims or thin off cuts to create a barrier between your clamp and the workpiece. I will definitely look to purchase more if/when I get a bigger MFT table.

Works well and locks things down rock solid, I'm using with a Bosch workbench and they fit well in the 20mm (?) dog holes, doesn't fit into 19mm dog holes on my main bench. Look at the picture and work out how to use them - there's no guidance on the package.

I think my title says it all. I use in home made dog hole about 50mm deep, these clamps work great. Delighted with them

A bit fiddly and not up to Wolfcrafts normal standard.

Simple, quick, efficient bench dog hole clamp. Why have I not had these before? Got two pairs might get more. A very good clamp for the job it is intended for. (didnt intend the rhyme)

I can understand why some other reviewers criticised the lack of instructions. There is a little 'how to use' on the packaging but it isn't great. However, after a couple of goes, these are quick and easy to use. They hold items safe and secure.

quite like these really, solid enough, like someone said they are not g-clamp tight. They come with no instructions, each clamp is made of two pieces, the section shown gripping the wood goes (A) into your workmate (fits my black and decker well), the second piece (B) has a lug that fits down the gap left between the leg of A and the side of the hole. The leg of A is cam shaped thus on when you insert lug of B where you can and then rotate it horizontally (clockwise I think) it cams the A tight into the hole at whatever height you have set. It doesnt cam the clamp downward but give a snug enough fit for extra grip on the work piece. Pretty good and unobtrusive when not in use.

Only good for light work. D clamps are more secure.
