C.R. LAURENCE Comp. #SC6 Suck-N-Clamp. Lot of 12 Counts

I used these and the Rhino Glue (cyanoacrolate) in the "Brush-On" bottle re-glue the glass on my 2010 Mustang GT. The brush in the Rhino Glue bottle was very important to get the liquid glue up under the tight spots where the fabric had pulled away from the glass and the heat tape that was used to originally attach the glass to the fabric top. Just make sure to protect the glass with tape (I used clear packing tape to catch any glue runoff), and apply these clamps fairly quickly before the glue sets (it's best to do a "practice run" to finalize the clamp positions before going "live" with the glue). I found that using a thin strip of wood (like a paint stirrer) and two of these clamps would work for straight sections - try not to do too much at once; just work your way around and do a corner at a time, and allow the glue a couple of hours to set up solidly. Some might want to use the 3M glue (much more expensive), and that's their choice, but the Rhino glue worked well for me - just make sure to get it clamped down tight before it starts to set. Areas exposed to humid air might set quickly, while areas that soak into the fabric will take a couple of hours to fully grip - be patient! I also followed up a week later with a thin bead of Permatex Clear Silicone to keep water out. Thanks to the other reviewers who gave me enough courage to do this, and it saved me a bunch of money.

I used a set of 6 of these to re-seal the window in my 2009 Audi A4 convertible roof. They suction to the glass very well and absolutely secured the glass while the sealant dried and cured. The wing nut and screw is a bit on the cheap side, but it functioned as promised and I had no issues at all with it. You can use a flat piece of wood or metal under 2 or more clamps to even and spread the pressure and you can get solid pressure with these clamps. Worth the price, they saved me a lot of money for the convertible roof window repair.

I bought these to hold my convertible top window after applying 3m window weld to reseal it. They really hold well for hours if necessary. I had to reach under the cup with my nail to release them.Notes:1. They have 3 holes to allow you to adjust the length of the hold down from the cup center.2. Caution, these can be tightened down to apply a lot of pressure to the glue point. If you are using a product like 3m window weld - don't tighten them too tight, or you will force the window weld up through the convertible top material, and then when you remove the clamp, you will have a stain on the convertible top material that is near impossible to remove. Use the window weld sparingly as it really holds well, and just tighten these down so that you make a light touch contact. You also don't need to leave them on too long, so you can start taking them off after the window weld gets tacky. If you need to re - seal the entire window, you should probable buy two sets of these.

I've recently bought a second set of these suction cup clamps to help repair the window on our convertible. These are a must to have when doing such a repair because it allows you to spread out pressure across the top when trying to glue it back with the rear glass window. I've tried other methods to apply pressure on the top, but these are by far the easiest way to do it. Well worth the money! I've also removed suction cups from the "bar" apparatus of the clamp and used the suction cups to hold up the driver window when I've had to replace the window regulator on a vehicle - beats using tape to do it! These are definitely handy to have.

i used the 3M windshield glue and primer - I supplemented these suction cups/pushers with aluminum rulers - all the materials to do the job came to about $80.00 and i did it in two nights - bottom and sides one night - top the seconded night

These suckers are awesome. I bought them to re-attach the rear glass in my car's convertible top, and they did exactly what they are supposed to do. The suction cup grabs on to the glass (clean it first, and a little moisture helps here), and the wing-nut allows you to tighten the clamp so as to press and hold the cloth in place while the glue dries. Obviously, this item has very limited use, but if you have a situation requiring a suction clamp I can think of no negatives here.

This is an excellent product that functions as advertised. I probably could have used eight instead of six, but six did the job. I read reviews that complained about some of the clamps not sticking to their window. I had zero problems and these worked well. They suctioned to the window and stayed put overnight. They clamped down with more force than I expected. I would not have been able to do the rear convertible window repair without these. I repaired the rear window on a 2008 Mustang Convertible.

If the cloth on your convertible top comes loose from a glass rear window it is difficult to glue them back together. These suction cup clamps hold the cloth against the glass until the double sided tape or glue you used is fully cured. Ideally, more than 6 would be recommended. I did a section at a time with the six pack but if I had to do it again I would have bought 12.
