As we all know, to generate force, we need to apply a load. So, when we apply a load on a spreader clamp, it exerts an equal and opposite force that helps us to open or separate things.

When you want to use a trigger clamp as a spreader clamp, you must use one simple trick. Remove the removable jaw from the bar and put it back in the opposite direction. So when you trigger the clamp, it will go in the opposite direction to create the opposite force.

If you are using a bar clamp, you must modify it. Take out the screw which is used to adjust the jaws and put it back in a way that both of the jaws are pointing in the same direction. Now you have to trigger the clamp to open up things.
