FCHO Glass Suction Cups Heavy Duty Aluminum Vacuum Plate Handle Glass Holder Hooks to Lift Large Glass/Floor Gap Fixer/Tile Suction Cup Lifter/Moving Glass/Pad for Lifting/Dent Puller (2 Pack)

I was impressed with these out of the box for the money, they seem really well made, not cheap junk. I left them overnight on a heavy porcelain slab and was able to lift it the next day without resetting the suction. The suction cup surface has soft feel that really seals well, and the amount of suction possible by pressing down a little before flipping the levers is impressive.

Funcionan muy bien

Seems strong and sturdy.

Used these to install commercial HEAVY glass units. 1" thick glass windows that were at least 150 pounds and these felt sturdy and kept suction.

No los he trabajado pero me parecen bien resistente
