DAMO 10" Vacuum Suction Cup Heavy Duty Glass Lifter with ABS Handle and Hand Pump Suction Cups for Glass & Granite Lifting

DAMO suction cups are very sturdy and reliable - they never slipped. Used for moving my 300lb aquarium and worked flawlessly! Worked better than my expectations and as advertised. No slipping and easy to use. Just pump the plunger til it can't pump any more and its ready to go. To release, just push the lever on opposite end of pump. Highly recommended! Truly heavy duty!

Works great we use it on marble slab weight over 1000 pound still hold up. Of course it’s not hold up by 2 cups. But very confident in it. I wish it’s metal but even it’s plastic still amazing suction and feel strong.

Excellent tool, but VERY cheap case. The catch that keeps the case closed is flimsy and brittle. It broke on the first day with very little pressure.

Definitely heavy duty accidentally popped it off 7 stories in the air bounced off a concrete poured wall and landed on the ground flew into some pieces but was easily put back together and works great unbelievable

OMG. If you move heavy sheets of anything slick, these are a must have! Bought these for a window install project. After struggling to hoist the windows off the truck at delivery, with two big strong men to help. Two women carried four different sets of 7-foot wide double-paned, mulled-together, double hung windows up a flight of stairs (they're about 200 pounds per window) and installed them by leaning them through the opening then pulling them back in. Whew. Thank goodness we had these suction cups!Yesterday, I needed to move some heavy folding tables. Noticed the nice little blue box of suctions cups on the shelf in the garage as I was debating whether to wait until someone else got home. I used them to carry folding tables by myself. No Problem!Love these things!
