AccEncyc 6 Pcs Strong Thickened Sucker Suction Cup Clear PVC Sucker Pads with M6 x 14 Thread Screw Extra Strong Adhesive Glass Suction Holder

We got these to upgrade an inflatable which attaches to glass... we also used a pair to upgrade a sunshade. Both applications worked amazingly well! The suction cups are very thick and strong, the threaded posts made it easy to attach through an existing grommet or through fabric. These are high quality and stick to glass with great strength.

Strongest suction cups I’ve ever bought. Placed them on windshield for emergency lights had to re adjust and they stuck right back on. You have to clean your window first it’s a must for the best adhesion

Very sturdy. I purchased these to attach perches off our window and in the shower for our bird. I don’t have to worry he is going to come off the window at all.

I used these in place of those stupid "No-nail" adhesive stickers. They work really well for quite some time, but unfortunately, I keep having to re-adhere them to the surface from time to time. Not the end of the world, but I do wish I didn't have to do that. Other than that, they're heavy duty as advertised, very thick material, and feel pretty sturdy.

I have an old hand operated meat slicer from the 1950's. and it's rubber suction cup feet had hardened and cracked. When I turn the hand crank to rotate the slicing blade, the whole slicer would slide all over the countertop. I used these suction cups to replace the feet on the slicer. I had to tap out the holes where the old feet were mounted, but the new suction cups use a widely available 6mm x 1.0 thread, so it was easy to find a thread tap that worked perfectly.Now with these new suction cups installed, the slicer works like it used to over half a century ago. When i place it on the counter, it sticks itself in place and holds securely. It would have been a bit nicer if there was an easy way to get the suction to release, but I didn't think to look for that feature when I bought these. Overall, while it's a bit hard to get my slicer to let go of the counter, it stays where I put it while I'm using it, and that was what I wanted from these suction cups.For what I am doing with them, I don't need the suction cups to hold for long term attachment, as I might if I tried to use them to mount a shower shelf. I can't say how well that would work. But for short term usage - like an hour - they hold very strongly. Overall, they are exactly what I needed.

Awesome product

A 3 weeks ago, I bought 3 cat beds that suction cup to my windows. I had problems with them staying attached, so I purchased 2 packs of 6 heavier duty cups to replace the ones that came with the beds.They didn't stick very well from the beginning, however, I checked them several times a day and reattached them when needed.Today, they continue to fall off my windows and my cats won't use the beds any more.Don't buy products made in China. Not worth the money.BTW, the beds weigh about 2 pounds with 6 cups holding the beds.

Seemed like a good product. Have been using 2 of the 6 since May 2025. It is now September 2025. One is being used on a flat surface and there are no issues. The other is used on a wall holding an apron. Today it fell off the wall and won’t re-stick.
