Stop straining your back trying to lift heavy stuff... suck it up! With our suction cup, single or double or four, just fasten the suction pads to any non-porous surface and move it, lift it, place it, transport it... you decide.
For the Four Head Suction Cup Lifters, press the levers down to create a strong, continuous hold. Lift up on the levers to break the suction.
Theory:
The working face of the suction cup has a curved surface. When the center of the suction cup is pressed against a flat, nonporous surface, the volume of the space between the suction cup and the flat surface is reduced, which causes the fluid between the cup and the surface to be expelled past the rim of the circular cup. When the user ceases to apply physical pressure to the centre of the outside of the cup, the elastic substance of which the cup is made tends to resume its original, curved shape. Because all of the fluid has already been forced out of the inside of the cup, the cavity which tends to develop between the cup and the flat surface has little to no air or water in it, and therefore lacks pressure. The pressure difference between the atmosphere on the outside of the cup, and the low-pressure cavity on the inside of the cup, is what keeps the cup adhered to the surface.
