IMT 8" Glass Suction Cups for Granite & Glass Lifting, Vacuum Suction Glass Lifter with Handle, 240lbs Load Capacity W/Free Case

My company purchased 8 of these for installing glass architectural wall product and they work great. We use them to move and position very large, heavy sheets of up to 1/2" glass, weighing up to 400-500 lbs. With two men and 4 of these grips we have no problem. They suction to the glass with ease and release with ease, and they are very sturdy and have strong grip. They each come in their own plastic hard case for storage which is nice, because once they are damaged you pretty much have to replace them. The case helps keep that from happening.

I bought these to move some of my larger aquariums. I just moved a 135 Gallon aquarium and the suction cups worked flawlessly. (weight is around 230lbs.) The cups attached easily to the glass sides and the tank was carried to its final location with no problem. The release valve is positioned to minimize any accidental release. The valve worked fine when needed and the cups were easily removed. I used 4 cups, 2 on each end. I would highly recommend to anyone in need of suction cups to carry an item.

Did the job I was looking for on heavy wood windows. Two on a 360 lb. picture window held fine. Must be kept clean in the provided case.

I just needed a basic, nothing fancy suction cup to help me get a custom-made storm window out from over my kitchen sink, worked perfectly. For my needs, as long as the old suction for 2 minutes I'm fine with it.

Good price for good working tool.

I have used this product to glaize my 150 year old single pane windows. It holds 36”x40” glass securely enough that I can carry the single pane down a ladder at my side. In 20+ repair jobs it hasnt dropped one yet

Been using it for past couple of months, and I like it quite a bit. Good quality and suction holds

I have to install 18 windows. I had bought the cheaper ones without the plunger and let's just say they lack holding power. I picked up this unit(and a different brand of the same size-they appear identical apart from the box). These things are nice! I had to bring two windows to the second floor and the stairs are not yet installed. We tied a rope around one of these and hoisted. No broken windows. They held firmly.
