Product Description

Use the cup on clean, relatively smooth, nonporous surfaces, at temperatures from 10 to 120 Fahrenheit . Moisture or contaminants can reduce the slip resistance of the cup. The red-line indicator may not perform reliably at elevations above 5000 feet.

To Attach
1) Position the hand cup on the contact surface so the red line will be visible if it should appear while lifting the load. CAUTION: Test the cup for staining or deformation of load surfaces with light colors or soft coatings.
2) Pump the plunger until the cup attaches completely. When the red line is hidden, vacuum is sufficient for lifting.
3) Check the plunger frequently to make sure the cup remains securely attached. If the red line appears while lifting, set down the load immediately and pump the plunger until the red line is hidden again.

To Release
1) Set the load on a secure support.
2) Press the valve release lever until the cup disengages completely.

Maintenance
Since aging and wear reduce the capacity of the rubber pad, it should be replaced at least once every 2 years or whenever cuts, slits or other surface damage is discovered. Always inspect vacuum pads before use. Clean vacuum pads and the load surface between each lift. Make sure both surfaces are dry and free of any dirt or obstruction. Make sure plunger has enough lubrication for pump.

Warning:
Do not use suction cup for climbing nor pull ups!

I bought these for moving a heavy aquarium. I had to move the aquarium twice, with two separate friends. Both times, each friend exclaimed how happy they were that I had these. They make gripping large unwieldy items MUCH easier.
Believe the great comments about this product. Just ordered a $400 aquarium and used this product to grip the cage and it worked perfectly! No slipping and easy to use. Just pump the handle til it can't pump any more and its ready to go. To release, just push the lever on opposite end of pump. Works wonders! Highly recommended!
I'm remodeling my mobile home, and wasnt too concerned about the window installation. Taking out the old windows was no biggey as i didnt care if they broke, but when it came to the new custom made double paned windows, and ironically these "suckers" went on sale, i bought one. thank god for speedy shipping as after i got one, i liked it so much i got one for my wife so she could steady the window while i climbed up the ladder to install. I bought this type as its the type the glass guys i know use and now i see why. I wouldnt waste my money on an iffy product if your dealing with new stuff. If it fails, you'll most likely be looking at glass art. The fact that it has a visual to let you know when you have good suction and a manual release is invaluable. you dont want to be guessing if its got good suction, or be jerkin your unattached window around trying to peel off the suction cup. I was playin with them when i got both with my countertop as it advertised grabbing granite. the countertop was still attached and i pulled as hard as i could. The countertop groaned but the suckers held. BTW Im a bricklayer by trade and am much stronger than your average joe. I wont be buying any more as im sure these will last my lifetime with proper maintenance (if any).
Worked as represented. Used to remove broken thermal pane window and replace with new window. Good value. Red line indicates when vacume is failing.
As a remodeling contractor I need to remove large pieces of Glass and Mirror in the scope of our work. In the past I use to borrow a set of cups from a glass shop to do this. I decided to get my own set and found they were super expensive. I found these Damo cups online and the reviews said they were as good as any out there...well I have found that to be true, these are great cups at a great price.
I bought a pair of these suction grabber's for moving large sheets of etched glass. These panels were $25,000. each, and I was understandably nervous about my reputation, as well as possible reparation, had anything gone wrong. The tool was easy to use, didn't slip, and provided visual affirmation of suction via the colored thumb-pump button. Lightweight and easy to use, had no problem with them.
I searched locally and online for this type of suction cup and these were the best prices units I could find.
I already owned a "woods" brand cup and it is identical in quality to this unit but cost more than twice as much !
These are top quality suction cups, and I am already ordering another.
