Woods Powr-Grip N6450 10" Concave Vacuum Cup with Metal Handle

Great for picking up smooth heavy objects.I find that when you polish the surface with Pumice powder 4F Grain Filler it creates a smoother surface for materials like antique glass in which the suction is even better. It turns out that you can even seal porous materials like wood with dewaxed-garnet-shellac-flakes you can pick up smooth heavy wooden objects like dressers as well. I mixed up some dewaxed-garnet-shellac-flakes with some Pumice powder 4F Grain Filler to make a paste to fill in oak grains on a piece of furniture I built until it was perfectly smooth and then used the suction cups to carry the newly made furniture up several staircases with no damage. Everything turned out perfectly and I will use this method again in the future. Thanks for making a quality product.

I use these grips when installing shower panels, mirrors, etc. They have a very powerful grip to the point I am surprised how much weight I can manage with them. I clean the surface of the panel to be carried, apply a tiny bit of water around the rim of the grip and apply suction. Works every time and last for years.

Fast delivery, reasonably priced, and my guys can use it this week! Thank you!

Works great

I bought two of these for removing large annealed removable third glazing panels from windows I am refinishing. The first panel I used it on I pumped it up to the level recommended by the red line disappearing and pulled the glass panel out and set it down for a couple of minutes without pulling the cups off and suddenly the glass panel shattered. This was a a double strength annealed glass panel. So I recommend that you hesitate to pump this up to the max with double strength glass and remove the cups immediately. The 10 inch is probably overkill for double strength glass. I like this lifting cup. It does not come with 2 oz. spray bottle of MaxTite Waterbased Clean & Defend Suction Cup Cleaner and a 12 x 12 in. microfiber cleaning cloth.

works grate for lifting a new machine window in and out will oder again if needed

This is a quality unit. One major problem. In the description it should state “minimum 1/4” glass. For window glass it is too much volume of vacuum and breaks the glass. I returned the 10s and ordered 8s

I purchased the cups on 01/06/2025 use them for the first time mid February, end of February broke my first window glass , on 3/2/25 broke my second window glass while I was installing it , I had glass all over my self and small cuts on one of my arms ,3/5/25 contact it the seller to get a full refund and they denied, toda3/6/25 I contact them again to get a replacement maybe is just this one's and other ones are good ? They denied the replacement!! I don't recommend buying from them !!
