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

Worked well. Strong and stayed for several months outside without coming down. Even with squirrels climbing up it. Went back up and set since

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.

Very similar to the DANXQ ($2.50 ea), both 55mm diameter with a M6 bolt & nut (basically a 1/4-20). I hung a 5 lb. weight using a small chain from a metal ceiling plate (not glass smooth) using 1 suction cup. AccEncyc held for 139 mins. - DANXQ for over 3 hours. The AccEncyc are good, but the DANXQ appear better and seem a little more heavy-duty. The AccEncyc have stainless steel hardware, the DANXQ do not. There are also other comments that the DANXQ are not UV resistant for outdoor use. Either will serve my purpose of attaching a tarp to the side of a teardrop camper using 5 suction cups. 3 AccEncyc did hold a 6 x 8 tarp to the side of the camper for several hours on a windy day with no problem. I did not have the DANXQ at the time. NOTE: Results are best of 3 test. The metal surface and the “sucker” were cleaned with a damp microfiber cloth before each test. There was obvious improvement in performance with each test cycle, probably due to “sucker” oil (plasticizer) reduction.

These suction cups are great. I am using them to hold up a curtain and they easily hold up the weight. For how strong my they hold I was pleasantly surprised how easily they can be repositioned.

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.

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.

These seem to work really well.

Just what I needed! I had some clamps I bought from Amazon that had 2-1/2" cups that would not hold more than 1 min. on glass! So I purchased these cups and with some extensions, I modified the clamps and was able to re-glue my rear glass window on my convertible back to the top fabric. Thanks to Amazon, they had everything I needed to make something that would work!

屋外用監視カメラをガラス窓に取り付けたくて、約5年前に購入して取り付けましたが、直射日光の紫外線を浴びても台風が来ても雪が降っても黄色く変色していますがくっ付いている状態です。まだこの先もくっ付いていそうですが、外壁塗装の関係で外したので新しく購入し直すことにしました。くッ付ける面が良ければずっと付いてますよ!!

Used them to mount a luggage rack on a vintage car. They have been good so far

Good Product, works well so far. They were purchased se help Christmas decorations from swaying on the hook ( which bears weight ) they are on. Will have to wait an see how the handle the cold weather.

長期在庫っぽかったかな。 吸盤を洗剤で洗ってから ご使用下さい〜。 床にもちゃんと強めに 装着出来ました。
