Crash!!!! My sink detached from the countertop (thanks contractor). I found these on amazon and saved my bacon. Easy to install and made the sink-countertop more stable than before. Well worth it and would highly recommend these.

I bought and installed these back in February 2017. 3 years later, the mounts are still holding my sink in place with zero issues to speak of. Back in 2017, my stainless steel undermount sink was sagging because the silicone caulking bead between the edge of the sink and the granite countertop was cracked and water was seeping onto the plywood supporting the sink. I waited entirely too long to replace the caulking and as a result, the plywood rotted.The Cinclips was a very simple install. Push the sink back up in place, mount the clips in the desired location, mark the holes for the Cinclip base mounts, drill the holes, screw the brackets in place, and that's it. You're done. Obviously, the cauking around the sink has to be redone with your silicone based sealing agent of choice.I'm sure other people might encounter difficulties based on their kitchen cabinet setup. I was fortunate that kitchen cabinets are modular with vertical boards located 2" to the outside of my kitchen sink, providing me a perfect location to mount the Cinclip bases. Overall, including recaulking, I remounted and repaired my sagging sink in about 1.5 hours total.So long as I keep my sink sealed and the supporting structure completely dry, I have no doubts that the Cinclips wil last the life of my kitchen and I will not be plagued with the problem of a sagging kitchen sink ever again.

These are awesome! I have a heavy, custom stone sink and I wanted to put one more support on the back. Not even sure I needed it but I figured better safe than sorry. When I reached out to the company they shipped me another immediately. This is the one you want, and you can feel good about getting a quality, made in USA product from a quality business.

So the bottom/left side of my undermounted sink came loose from the quartz countertop. The absolutely worst spot to reach due to the disposal and sprayer hose. But I'm not an overly handy person, so there was no way I was going to remove everything. I squirted some clear caulk between the sink and the counter (where it was gapping) right before I started. I put a pillow down on the edge of the cabinet to keep from killing my knees, knelt inside, and pushed the sink up tight against the counter with my back/shoulder. I used a compact drill to screw in the cinclips. I went ahead and put them all the way around the sink, because I have no doubt the rest of the sides will be coming loose soon. It was a really tight fit and there was some groaning and cussing involved, but I managed to get it done. I know this isn't the ideal/perfect situation--it should have been pulled down/resealed/reinstalled--but I simply didn't have the money for that. My sink isn't falling to the floor and it isn't leaking around the edges either.The only negative thing I have to say is that there wasn't a lot of space between my sink and the ledge of the counter, so some of the clips had to be positioned almost straight up and down. It seems like this doesn't give as much support as the ones that are installed at an angle. One of the vertical ones even popped apart when I was installing it and I had to put it back together. Overall, though, it seems substantially more secure than gluing.

These may be one of the easiest, and most cost effective, ways to remount a sink. Let me explain:My kitchen sink recently pulled away from the silicon sealant, and the mounting brackets were improperly mounted and sized for the weight of the sink. The mounting brackets had actually bent about 15-30 degrees each, the right side of the sink on the worse end of that range.I had tried remounting with new brackets but ended up with them bending as well, much to my surprise. To be fair, I frequently fill my sink with about 7 gallons of water and will do a week's worth of dishes in a single sitting. Not the best plan if the sink isn't secure.So when I was told that these cinclips would mount into pressboard and hold my fully filled sink, garbage disposal and associated plumbing, I was skeptical. And it turns out I was wrong.They are shockingly sturdy for what is only 4 plastic mounting brackets (5 when you use the rear/front short bracket) being held into pressboard by 4 screws each.They are almost as easy to mount as the company's tutorial video depicted. Yet another surprise.My only issue was the short bracket that I had to install in the rear of the sink, which was a construction problem unrelated to this product. If you do not have about 4 inches of front cabinet to screw the bracket into, you may be stuck manually attaching the 4 screws on the short bracket while working behind your sink in a space only 3-4 inches wide. That being said, many other users said they didn't even use the short Cinclip.And use gorilla tape to hold up your sink while installing it. I opted for duct tape, and decided after installation to read about the difference between the duct and gorilla. In testing: gorilla tape is stickier, holds more weight, and is more water resistant. All good things for a sink project. In practice, I've still never used gorilla tape so I'm going on recommendation.The cinclips have now been installed for a month. The sink did initially settle about a quarter inch and pull away from the silicone I had used as a sealant. I reapplied the silicone 2 days after installation and have had no peeling away since. I believe this would have been avoided if I had gone with the gorilla tape and not the duct tape.Should I ever need to remount another fallen kitchen sink, I will most likely use the cinclips system again. It's simply too convenient, especially given that it can be used the same day as installation.**Update 10/23/16**My wife and I moved into a new house this year, and while doing the inspection I realized that the kitchen sink was IDENTICAL to the sink in our old home. Looking underneath the sink I saw the 4 brackets were also identically installed. Having spent about a year with my previous cinclips not giving out, I opted to buy and install them before the sink could peeled away. It took me 5 minutes to install the 4 brackets compared to the 2 hours it took for me to remove the old brackets from the sink, clean the caulk/silicone off, remove the overtightened garbage disposal fittings, clean up the resulting water, reapply caulk, tape the sink, and THEN install the cinclips.If you have the option, install these before you have problems. It was so much easier ;-)

We recently changed our kitchen countertops and sink. Having read way too many stories about sinks beginning to become unglued from the countertop, I wanted to add an ounce of prevention.... Many readings later, I landed on these.I particularly appreciate these supports as they fit perfectly for our application. Very simple, fast and easy to install. Pretty much only requires an impact driver or screwdriver to install with the included 3/4 inch screws. Screwed directly into the interior sides of the cabinet beneath the sink. My wife was worried they would impede on the space in the cabinet below the sink. They absolutely don't. The supports are made of heavy and sturdy plastic and basically are there as back up to support the weight of the sink and it's contents.I would definitely buy again and not hesitate to recommend.

Arrived on time, great product if you have sink garbage disposal

Easy to install but need to make sure the brace is held secure prior to screwing it in. The 5th support is small and no able to install on back as there is no access to screw it in.

I searched low and high for a product to support an under mount sink, my counter top is stone and I was weary about drilling into it to use the under mount clips, this product installed in seconds and provide better support than clips, they give you five brackets, four long one and one short one and I didn't even use the short one.

I'm very happy with these clips.My undermount sink got detached after about 10 years. All that was holding it up was silicone caulk.I looked around for brackets or other mechanisms to hold this up. I couldn't find anything that would fit properly. All that was left was to build a frame using 2x4s.Then I came across these clips.They are awesome. It is a simple but very clever idea. The clips are a very strong kind of plastic, they feel very very sturdy. The hinge means that they will fit practically any cabinet.PS: it's true that it only comes with 10 screws, when there are 4 holes per clip (20 total). The instructions do say that you only need to drill the bottom two screws for each clip, so 10 is enough. You can add the top 10 screws for additional strength, but it says it's unnecessary. Still, I wonder why they would cheap out with this! Such a small detail, but it feels strange. Otherwise, everything is outstanding.
