Stop bar for glass blocks and stoneware
To divide exact rectangles and triangles is usually a bit difficult with pliers.
Here, the stop bar can help you in the future to easily divide 20x20mm tesserae into regular rectangles or small squares. Likewise, you can use it to easily cut triangles from stones. You can even loosen the screws easily and the stop bar can be converted for left-handed users.
The stop bar is best suited for Murano glass stones, Fantasy glass, Ceraton and all other small stones with at least 20x20mm.
The dimensions of the stop bar are 160m x 60mm.
