All models feature adjustable heights for the rubber-protected vacuum clamps, which are operated effortlessly with a pedal-valve vacuum clamping system that can hold all materials, shapes, and sizes with a powerful hold. Even heavy solid-wood doors or panels can be held firmly by the vacuum clamps. While the grip is firm, the clamp pads won't scratch or damage your workpiece; clamping materials like glass with no risk of scratches or breaking provides you with new possibilities and time savings that would have been impossible before.The Easy Motion system adds a foot pedal-operated hydraulic lift element to the table to raise or lower the tabletop.
