Glass Suction Cups 2 Pack 8 inch Vacuum Suction Cup to Lift Large Glass 330 LBS Lifting Capacity Heavy Duty Industrial Suction Cup Tools with Carrying Case, for Tiles,Windshield,Window

As a ham radio operator I do most of my operation in the field. I like to throw up a wire and I’m on the air. The problem is I can find a tree but having two trees to put an antenna across is somewhat a problem.I now can use these to help resolve the problem. I can throw my antenna over a limb and then attach the other end to the mounting grip of this tool that is connected to my car!The suction power is strong enough to hold the end of a long antenna wire.

Absolutely no complaints. I use them for setting floor tile and they work perfectly. The only issue I have is the carrying case is of the cheapest variety but for the overall price, and the fact that the cups work great, I can live with a cheap case!

They hold a great deal of weight without losing grip. Well made and durable for the money. Only thing I’d change would be the carry case design. They should be better made and should keep out dust and dirt with some sort of rubber seal around lid

Worked great for replacing 14 window Units at my Home! Highly recommended.

I bought these to help install large tiles. I stuck them on a marble slab, pumped until red line was gone and... one of them immediately rises to the top (maybe 20 secs) and the second one holds air for a few minutes. So I tried on new clean ceramic tiles and same thing. Wiped off the worst one but same result. Unfortunately, I first tried them at day 34 and can't return. The big issue is if one pops off at the wrong time it could hurt and/or destroy a new install. Lesson learned- I think for dangerous situations it'd be wise to have ones with a pressure gauge and maybe a name brand.

These glass movers are phenomenal! The only problem I had with it is there 8 inches around and I only had a 4 inch gap that was flat without a place for the air to get in so I couldn’t get them to hook on. So I had to send this back and order a smaller unit that had a 4 inch in diameter part that hooked to the glass, although my glass was, 7 feet tall by 5 feet wide. It had ridges in it that wouldn’t allow the suction cups to work. So make sure you double check the size that you have for the suction cup to adhere to Before you purchase the size of a glass mover you need.

1 was not working out of box, the other would not hold over time

I used these to move around several very large double pane sealed window inserts around, and we had to make sure they were kept only an inch or two off the ground in case of slipping.
