Serene Valley Undermount Sink Clips, Sink Brackets and Supports, Undermount Kitchen Sink Clips NSA104 - Heavy-Duty 10pcs Kit

Had just moved into a 30 year old house and after just a couple weeks the kitchen sink fell in! Had no idea how to fix this, I wasn’t about to drill holes into the underside of my countertop to install new clips. I found these glue on clips on Amazon and they did the trick. Not exactly an easy project though. I had to scrape off all the old silicone, and scrub the underside of marble countertop with alcohol and a wire brush to make it as clean as possible for a good epoxy bond. I decided on the clip spacing and marked their locations on the counter top with masking tape. Then I used Gorilla 5 minute epoxy to glue on the clips to the underside of the counter being sure to leave enough clearance between the lip of sink and the clips. I found I had to use clamps to hold the clips on until the glue set or they would fall off. After letting the glue dry overnight, I used a bead of silicone around the top of the sink and then braced the sink from underneath, not trusting the clips to exert the firm pressure I wanted to maintain on the sink until the silicone dried. Finally, I snugged up the clips and removed the under sink braces. Between the clips and the silicone adhesive, so far, so good. Been about a month and a half now and the sink works great! Update: it’s been about a year since I did this project and the clips are still doing their job. I had one clip fall off after a couple weeks, but it was one I wasn’t able to glue on firmly to the underside of the counter due to old adhesive from the original install that I couldn’t get off and I t created an uneven surface for the clip to adhere. The sink still seemed secure, so I just left it off. We use the sink every day and I have no doubt will give us many years of trouble free use. Still very happy with the results.

Bought a home and the undermount sink was loose. Found it wasn’t sealed properly and only had 3 brackets holding it up. This style bracket allowed me to mix up some epoxy and lower the sink to the bottom of its existing 3 brackets and then epoxy in 2 additional bracket bases. After the epoxy dried I put on the other part of the bracket. I put in clear silicone between the sink and counter top and then tighten up all the brackets. It holds the sink very securely!! The only problem I had to buy 10 and only needed 2 but they were still easier and cheaper than me having to remove the whole sink to grind slots to use the standard ones. These worked great!

sink hasnt collapsed 6 months later, 5 stars

Used 4 of these for my undermounted bathroom sink and seems to be working great! I’m wondering about the holes in the design as it made the epoxy application process a little more messy than I’d liked. Apart from that I’m confident it’s going to help secure my sink

Ok these sink clips are 1000 times stronger than the cheap clips that the counter top installers provided when they installed my counter top and sink. Preparation is key when you are ready to install these brackets, if you read some of the one star reviews the failure is these brackets sticking under the counter top, the hardware won't fail unless you decided to stand in your sink. My first attempt I used JB weld and some of the brackets didn't stick, so I cleaned the area where I wanted to attached the bracket (dish soap and rubbing alcohol) then I took some 100 grit sandpaper and sanded the area, I reapplied the JB weld and held tight. If I were to do this again I would try a different sealer, maybe supper glue or flex seal as JB weld didn't seem to adhere to the stone, which it claims on their package. All in all these brackets our made of good steel and are very strong. Hope that this helps.

Was very happy with them until I tested how much they could take... Basically I cleaned, sanded and alcohol and acetone cleaned the counter underside and I degreased both sides of the clip bases. When torquing the clips up to squeeze the RTV out and reasonably tighten the sink to the countertop, two of the clips pulled away from the counter. Investigation revealed that the epoxy grabbed the quartz countertop very well but had absolutely no adherence to the clips. Any remaining epoxy on the stud side of the clips just peeled away with ease. I did not expect this issue and maybe a different style of epoxy would have adhered, but if I ever have to do this again with the same clips, I would sand both sides of the clip bases before cleaning and installing. So basically, if you don't take steps to make the bases stick to the epoxy, you are counting only on the surface area of the epoxy coming though the holes in the base, to hold the clips. With this consideration, depending how flexible your specific epoxy is, after setting for your planned amount of time before loading, a slight twist of the base after the epoxy is pressed through most/all of the base holes, will definitely make a difference in end strength of the slips holding power. I used the largest spring clips (~3+ inch throat depth) from Harbor Freight and they worked great to hold until set.

Incredibly helpful for bathroom sink install Great quality, well made!

Awesome price and quality. Helped me put my sink back up without any problems.

I removed my under-mount kitchen sink caulk without realizing its wooden support had rotted away. I ordered these clips as the new kitchen sink support and attached them with 2-part epoxy. It's been 3 weeks and it's holding up well so far. The clips look sturdy and are easy to install. Would recommend it for people in similar situations.

El material esta un poco delgado

Solved the problem with a badly installed under-mount sink. Tried all the big home improvement and hardware stores and Amazon was the only place I could find to purchase this product.

recommended bonding glue doesn't work and dropped off with loading. waste my time and money.

Worked great for my undermount sink!
