xTool P2 material clamps can work with materials with a maximum thickness of 12 mm.
You can use them as follows:
1. Place a board or sheet on the slats.
2. Stretch a clamp by holding the lower part with one hand and pulling the upper part up with the other hand, and then place the clamp around the material and a slat.
3. Fit the other three clamps in the same way.
