Compared size-for-size to other small clamps, the C-clamp is unmatched when it comes to clamping pressure. For those occasions when you need all the clamping muscle you can get, the C-clamp is hard to beat. Small C-clamps are handy in tight spots, such as clamping a fence to a router base.

The main drawback to a C-clamp is that it’s slow to adjust. Also, C-clamps don’t come with clamp pads. You’ll need to add them to avoid denting the workpieces.

A medium-duty Adjustable brand is a good choice. I found it produced about 1,100 lb. of clamp pressure. If that’s not enough, a heavy-duty Adjustable brand will get you even more.
