Wall Strong Suction cup Absorption door handle Window Door Knobs GRAB White

This is a useful product when you need something extra to move glass around (such as a sliding door). One thing; first, unscrew the white ball from the unit. Then, push hard on the suction part against the glass panel. Now, re-screw the white ball tightly in place. This is what gives the item its suction!When done correctly, the unit works well and is quit strong.

When the window in my husband’s car started falling down, we stuck two of these at the very bottom of the window to hold it up. After a few weeks the suction cups fell off and we had to reattach, but we used them for over a year before finally selling the car!

This suction cup knob works wonderfully! We attached it to our sliding glass window in the doctor's office and every staff member loves it. I would highly recommend purchasing this suction cup.

I love this lil handle for my office door. I got these just to try it out since our glass door didn't have a handle on the out side and it works perfect. Easy to set up stays on very good doesn't fall off day after day using and pulling on it and it works perfectly. I had to get one for everyone in the office, well anyone with a patio glass door.

This is working great for what I need.

Does not stay where you put it. Tends to fall off after a certain amount of time, usually in the middle of the night. Very frustrating.

I bought these knobs thinking they were much smaller in size. As they are, they are about the size of a small door knob. I packged them up to return them and drove them to UPS. The shipping to return them was $128.00. Needless to say, I kept them as they do not cost nearly that much.

Made the old sliding glass door sooo much easier to open/close. Would recommend.
