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

They are strong and hold up well. The nut and bolt in these helps to create a more secure suction. These cups were the perfect size for what I needed support for. They are sometimes difficult to get to pull off. It helps to loosen the bolts. Great price.

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.

I got tired of installing/removing my older but still functional license plate-mounted I-Pass unit on my family cars. I read somewhere that my I-Pass could be used window-mounted inside the car, so I bought these suction cups with attached bolts to mount to my I-Pass device which already had screw holes. I carefully shopped for suction cups with bolts the size I needed. With just a little widening of the holes in the I-Pass, these suction cups fit. I tried it on my next trip with my I-Pass mounted in the car window and it worked perfectly! The suction cups held the I-Pass in place quite well, almost too well as it takes some effort to break the suction in order to remove the I-Pass.

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.

Very strong and well built, not cheaply made. Liked so well purchased another set

These work! A couple years ago I bought a parrot perch for the shower that came with really lame suction cups that didn't stay adhered to the wall and certainly wouldn't support the weight of a parrot. I purchased these hoping that I'd actually be able to use the perch for my dusty cockatoo who loves the shower. After drilling out the holes in the perch to accommodate the larger screws that are imbedded in these suction cups, the parrot perch is actually staying anchored to the wall and now useable. Thanks for a product that works! The screws are NOT removeable. They are imbedded inside the suction cup.

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.

I bought these to use on a window shield on my RV. I did not want Velcro on the outside or magnets on the inside. The manufactured covers are 250.00 to 300.00 dollars. I made the cover and used 8 of these to hold the cover onto the glass. I was concerned about driving and wind pulling the suction cups free. I have traveled well over 400 miles with this on the trailer window, and it has not moved one bit. The heat and cooling temps have not affected the suction cups staying in place. Would I buy this product again, defiantly would. So simple to put the cover on and remove the cover.
