Wood's Powr-Grip N6450 10" Concave Vacuum Cup with Metal Handle

Perfect for using as work positioning on wind turbine abseils.

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.

Wood's are very good Quality Power-grip cups. Works great ......So far no problems.

I ordered these for an upcoming project, they arrived extremely quickly, I don't think I've ever had something shipped so quickly from Amazon before so I was very pleased by that. Woods power grips are industry standard for a reason, they just do what they need to without fuss and they are more durable than many if not all of the other brands that I've used. Absolutely a must have for the serious professional.

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.

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
