Strong SuctionThe 8-inch vacuum suction cup has a double-layer thickened design, which has stronger adsorption capacity, and the maximum load capacity has been increased to 200KG, making it easier to transport materials. Non-slip handleThe high-strength ABS plastic suction cup is more wear-resistant and has a non-slip effect. It is also ergonomic, making material handling safer. WIDE APPLICATIONSuitable for lifting loads with smooth or flat surfaces. Including glass, ceramic tiles, marble, metal plates, etc. For people with reduced mobility, it can also be attached to the bathroom wall. Instructions for use Adsorption: Press the air valve button perpendicular to the object several times until the button is pressed, then lift the object with the handle. Pull: Tilt the air release valve to release air and pull. Specification: Material: Rubber + ABS Dimensions: 185 x 210 mm Maximum load: 200 kg Package contents: 1 professional suction cup Instructions for use: 1: Use the suction cup on a clean, relatively smooth and non-porous surface. 2: A red line on the piston means you do not have enough vacuum to lift the load. Press the plunger to draw enough vacuum into the suction cup until the red warning line disappears. 3: When the red line has completely disappeared, the vacuum is strong enough to lift heavy objects. Check the plunger periodically to make sure the suction cup is secure. If the red line appears while lifting, pump the plunger again until the red line disappears. 4: Press the valve release lever until the piston is completely released.
