Take the hassle out of moving large tanks with these handy suction cups sold by Anver Corp. Â The model HC-S108 suction cup is rated to hold 123lbs, has a safety ratio of 4:1 and is priced at $48.95. Â To use the cup, ensure the tank side is clean and free of dirt and grease, place the cup on the tank with the handle oriented for gripping, pump the piston and you are set. Â A simple red safety line on the grey piston pump shows when sufficient vacuum is created to hold the cup to the glass. To release the suction, depress the spring-loaded lever positioned at the other end of the piston.Â This allows entry of air, which breaks the seal releasing the cup. Â Each cup is molded from ABS plastic with a rigid handle and comes complete with a hard protective case. Â We have been using these cups for many years now and they are invaluable when safety and ease of movement are prime concerns. Â No more slipping of fingers and blackened fingernails from having hands under a tank. Â These vacuum cups from Anver are a must-have for individuals and clubs moving tanks on a regular basis.
