Review on Efficient and Versatile - POWERTEC 71164 Cam Clamp 20 for Reliable Holding Power by Allen Tchida

Haven't used them in a jig yet but have fitted them to an existing jig just to see how they work. They worked great. The aluminum is smooth and the blue anodizing is strong and strong. All parts appear to be of good quality. They worked as I expected, very well. If your jig can handle indexing handles where they don't get in the way, this is a very good solution for quick cocking.
