I'm using these clamps as end supports for my work bench. I like the size and adjustable levers. They come in handy when securing long boards. Although they are smaller them most clamps they do support the boards well enough where as only a minor clamp is needed when securing most of the boards before cutting or using a jig. I set up two clamps at the end of my 2ft wide table less than 1ft apart from each other close to the center. After raising the height of the clamps 1/2in off the table by securing a 2in X 2ft X 1/2in board underneath, it allows for thicker boards to be used and gives me a nice fine edge to square the boards for cutting. The clamps can be adjusted and locks in place and so far they have done their job. I use a lot of 3/4in wood and the clamps seem to hold them well enough on the one end.
