Very happy with these. I need them to be portable so screwed them onto a wooden strip then took them to college and attached them to table with a single central clamp. Raised table height with drawing board and the system worked perfectly, no movement, and arrived promptly. Why did I struggle for years without these?

Excellent genuine Speedball clamps. Arrived earlier than stated and in top condition.

These clamps make screenprinting multiple prints a doddle; they're heavyweight and feel quality - once attached to the screen and the work surface, nothing's going anywhere. Well worth the price.

Arrived promptly,does exactly what it should.

The real speedball units at a a great price. Really holds the frames well.

Ferfit just what my daughter needed

Just right .

They seem sturdy, but one of them seized up the very first time I used them . I was at a live printing event, and luckily towards the end of my print run when one of the clamps just stopped opening and closing and when I raised my screen, refused to bend and just pulled itself up and out of the wood it was fastened to. I have since oiled it to try to loosen it up, but it is really stuck and in no way as flexible as the other clamp. It’s so trustworthy I can never use it again. Very disappointed as Speedball products are usually good.

These hinge clamps are great

These are the same clamps I used for screenprinting in college. Now I can build a printing board of my own!
