If your reading this you discovered that your Dewalt came without a clamp. This is the mother of all clamps. Heavy duty is the word I would use. Fits perfectly in the oversize hole in your Mitre saw. Reaches over the oversize fence on your mitre saw as well. I tried to find any other manufacturer clamp to use as a substitute but no this is it for Dewalt. You 'have to' buy this one if you want a clamp. You either return the saw or give up and pay the ridiculous price. Is it a $80 part. No. Its more like a $40 part. Do you have a choice no. Do you need 2? I don't think so. Its massive. Has a quick release on the screw down. Good size knob you can work wearing gloves. Does all this make up for the price. No.
