Easy tool-free assembly on the machine. For narrow workpieces, the dowel can be positioned closer to the stop edge, allowing for a wider range of applications. The stop pins can be quickly folded out or in as needed. The machine's support area is enlarged, minimizing the risk of tipping, for example in edge areas. The included additional stop increases the support area and reduces the side distance of the stop latches to the center of the domino from 37 mm to 20 mm. This enables precise positioning of narrow workpieces.
