I bought this clamp to use as a shorter version of my 50" Tru-Grip clamp which is a similar design. Now I understand that the people who make Tru-Grip have gone out of business. the Tru-Grip was better than the Emerson C24 at my furniture store. The adjustable clamping surface, which runs the length of the clamp, tends to move along its guides with the SMALLEST contact when the tool is between the clamps, even when "locked" as instructed; It's a little annoying when you make multiple cuts of the same width and just want the clip to "stay fit" between removing the clip and reattaching it for the next cut.
