This is a great clamp. It's amazing how something so simple can be so poorly engineered, as in the case of the Chauvet equivalent (CLP-02). Let's A-B the two: The ADJ clamp bolt is aimed directly at the elbow on the other side, ensuring that the bolt is always perpendicular to the pipe you're clamping to regardless of the pipe size. This is actually not the case with the Chauvet clamp, which is offset slightly to the elbow, which causes a force on the bolt and threads perpendicular to the bolt direction, and causes the bolt to walk around on the pipe as you're clamping down. The ADJ bolt knob is very comfortable to crank down. The Chauvet one is sharp and digs into your skin. The ADJ fixture bolt is short and comes with a flat washer AND lock washer. The Chauvet fixture bolt has no washers and is actually too long to use with 234; truss as the bolt sometimes bottoms out on the truss. (The ADJ clamp also gives itself a little more room for the fixture bolt by not putting it directly under the pipe you're clamping to. So keep in mind your fixture will hang some distance in front of or behind the pipe (unlike an O-clamp)).
