When you just can't find a helper or a third hand of your own, you can use this handy-dandy C-Clamp to hold your work for you.
We've used this when twisting cords or making rope as well as for holding fabric. Our medium duty clamp is capable of holding over 1,000 pounds of pressure, but we've never gone even near that!
The malleable steel cast body is 2 inches. The screw and handle are copper plated to protect your project. The throat depth is 1-1/4 inch deep.
