Two-plate suction clamp set with a fixed left suction cup on the left plate and a movable right suction cup on the right plate. Setup and operation - Install the fixed (left) suction cup on the left plate and the movable (right) suction cup on the right plate. - Pump the piston until the suction cups are securely attached. - To join the seam, rotate the side knob counterclockwise until the seam has a seamless appearance. - To level the plates, position one of the blue heads under the top knob on the higher side of the seam, then rotate the top knob clockwise until the plates are level. Usually one top knob is sufficient; use two if expansion is needed. Key benefits - Provides a secure, adjustable hold for panel bonding, gluing, and finishing. - Enables precise seam alignment for a flush, professional look. - Simple, tool-free operation with clearly labeled knobs for quick setup. - Left and right suction cups accommodate different workpiece sizes and orientations. - Blue-head leveling system helps keep the work surface stable and flat. Use scenarios - Woodworking: clamping veneer seams or laminated panels during glue-up. - Glass or acrylic assembly: holding two panels flush while adhesive cures or during fittings. - Metal or plastic fabrication: aligning and leveling panels before welding, soldering, or bonding.
