BRIXWELL Adjustable Suction Cup Clamp Set for Glass Windshield Repair Kit with Suction Cups for Glass 6 Pack Hands-Free Tool for Convertible Top, Body Trim, Auto Glass Panel & Windshield Repair

The rear window of my convertible was coming loose at the bottom from the convertible top. Bought adhesive and these hold downs and they worked perfectly holding the convertible material to the window while the adhesive dryed. Make sure your window is very clean so the suction cups stay in place.

This product is a must for anyone looking to fix your rear convertible window. I did this once before without it a couple of years ago and spent a lot of time in the alignment of the glass. After 5 year I had to redo my window. I seen this product so I had to try it. Along with the “3M windo weld glue”. It was simple to use. The suction cups held great in a 105 degree garage. The alignment of the top and window worked great.

I had seen clamps like these while researching how to repair the rear window on my wife's Mustang. The window had come completely separated on the outside and perhaps 25 percent on the inside. I only purchased the one box of six clamps, so I used paint sticks to extend the holding area for the clamps. Due to the window being completely disconnected from the canvas top on the outside, I had to work the repair in sections around the perimeter of the window. These clamps held the canvas in place very nicely overnight while I let the glue set up. I did clean the window thoroughly before using these and also wet the rubber face of the clamps before sticking them to the glass. I was able to tighten these down firmly with none of the clamps coming loose over night. When I did the inside of the window, I had some trouble getting a couple of them to stay in place. However, all in all, they worked well and I was very glad to have them for this window repair. I just wish that the adhesive I used had held as good as these clamps! but that's for a different review.

I gave this one star so people would read the review. Probably should give it three stars. These are very cheap, buy any brand at the lowest price you can find. I'm sure they're all made by the same manufacturer. I overpaid because I thought Brixwell might be better.Most importantly, they left out a key part of the instructions. To get these to hold you must press the cup down firmly, all the way, and then tighten the wing nut until the center of the cup is pulled all the way up to the arm - as far as it can. Obviously the surface must be perfectly flat, perfectly smooth and perfectly clean. These are not high quality suction cups. I have suction cup mounts for iPads that work in car or plane windows and those will hold for weeks. These Brixwell type suction cups are not those. 5 of the six that came in my package have held for over 24 hours though and that's pretty good. The sixth has a flaw in the cup and will not hold for more than a few minutes.The pictures in the ad show the arm as having three holes for three different positions of the cup screw, but in reality it's a slot just like all the other brands.

Used them to repair an old convertible top glass, don't know how it could be repaired without these. The trick is to dip them in water, so the water stays in the suction cups. Get that located and stuck to the window, waiting about 10 seconds. Make sure the suction cup has grabbed, and then tighten the clamps. Might need to get more clamps! These actually worked great. A trick on You-Tube has you put paint stirring sticks under 2 clamps, so the pressure can be spread out. That worked great. Using this technique, these clamps all held overnight.

Bought for fixing my '04 Miata convertible window.YES it did work. But not like expected or advertised. I was able to use 2 of these at a time at the most.Spacing was the issue. The suction cup is so large verses the part that secures the glass means that 2 of these next to each other leaves a 3 Inch space between the glued down sections.So I ended up using only one on each side and slowly working my way in so I could glue all of the window, basically 1 inch at a time. If you get this you will immediately know what I mean.So I didn't need the other 4.But the end result is a very secure window that is back to being waterproof. Thus 4 stars.I would recommend it as it does work. I just can't see how you could probably use all 6 at one time and get a proper seal on the glass with the glue.

They did what they were intended for. Installed the glass back into an 03 new beetle convertible roof that had fallen all the way out. Use the recommended prep, 3m primer, and 3m window weld. For my job if I could have ordered more to make it go faster

They will not hold very good to the glass.
