IMT Heavy Duty Dual Vacuum Suction Cup Glass Lifter with Curved Pads, Strength Handheld Stone Handling Tool, 330lb Horizontal Suction Cup

These worked fantastically in moving some very large windows. After reading the reviews, I was nervous that some windows might be broken during the movement because the suction might not hold. I followed the instructions to the letter and they worked perfectly!

Works well so far. Hopefully it doesn't loose suction or else I'll be $$$🤯💩

We have some 60 lb. glass panes and these were perfect for lifting them up.

I had purchased this pair of suction cups specifically to move a ~50lb rectangular slab, er, sink vanity, made of pure porcelain into an area only as wide as the sink itself. It needed to be centered to the waste pipe. There was literally nowhere to place your hands on or under the sink to execute this delicate maneuver. I'm about the size of a sixth grader anyway, so this was going to be quite a logistical challenge.After placing a suction cup pair on each side of the porcelain countertop and assuring the vaccuum was tight, I had myself a nice little handle on each side which helped my execute this tricky task with perfection. I must admit I was constantly worried the vacuum would be lost and this thing would slip, but it held tight as I muscled it up and over the vanity.The only negatives I could say about this product are that I wish the length between each suction cup pair was adjustable, and that it had a suction loss indicator (which apparently some of their models do). But from my experimentation with the product, the suction vacuum on these cups is incredibly strong and in fact sometimes takes a bit of jiggling to let loose! It gets the job done.As a courtesy IMT sent me a free single 5" suction cup with mechanical lever suction action and the vacuum force on that one appears to be incredibly strong as well. It will suck on to whatever smooth surface you can give it.Overall, I am very satisfied with the utility of this little tool.

In general, these work pretty much as you'd expect. They "attach" fairly easily, hold well, and come off easily.The good:- They seem to have plenty of holding power.- They make working with flat things very convenient.The neutral:- Because they can work on things with a little curve (like a windshield), the attachment takes a bit of attention to get "right". Once the first suction cup is on, you have to be attentive to put the second cup on the surface flat before you apply suction.The bad:- As someone else commented, the "Safe Load Capacity" listed in the enclosed instructions is only 40% of what is listed in the description.

I use these to do windshields and they're great. The handles fit perfectly in your hands and the cups go onto the glass every easily. I can usually get them on in 1 shot with a little spray of windex. I would highly recommend these over the other orange and red handled branded cups.

The suction on these are great. I actually use these as boat handles and they stick to our boat with no problems! It holds my weight 155 pounds and solved our problem for me getting in and out of our boat! Worth every penny! Highly recommend them!

One piece of junk . Don’t waste your money, purchase something little bit more
