Very good quality and workmanship. Keeps in the truest sense of the word, what it promises. The terminal has a considerable clamping force. By adjusting the movable members 3 Dimensional camera is possible. The terminal know on a special form, so that they, too, thanks to the front end located and moving small retaining plates and the adjustable band (for example, rods) can be attached anywhere. Fully satisfied. Stable and Robust!
