Serene ValleyUndermount 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.

I got these to replace the marble ones that came with my vanity/sink. The marble ones didn't last long because of the weight and overall displacement of the adhesive. These clips get naturally surrounded by the adhesive you use and create an overall stronger bond. They are light weight and easy to use. Will use these are any other future projects!

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!

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

Bought these after another clip I bought here failed. The other clip was a two piece bolt/glue plate. This one has a solid connection between the mounting bolt and the glue plate. Having so many holes ensures good adhesion as the epoxy can ooze through and bind. Much stronger connection to my granite countertop.

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.

The sink installed by previous owners was coming undone. I installed these under-mount anchors on my granite slab a good 24hrs before installing the sink. I cleaned the underside of the slab where these are installed and wiped them down with alcohol and let dry. I used a syringe of 2 part epoxy (JB weld 5min epoxy 3900PSI) to dispense about a half dollar size of adhesive. Mix for about 1 min and then applied a bit to the bottom of the stone, and then dropped the anchor in the puddle with a twist. Put it up on the stone and wipe the forming drips to make an even layer around the bracket, keeping epoxy off the stud. I kept that up for about 3-6 minutes per anchor while keeping it pressed to the stone. After about 6min, the epoxy was cured enough to move to the next one. Tightenting these up made squishing the RTV around the sink base very easy. I hope the epoxy will hold for years, will update if anything changes. Recommend these for ease of sink installation.

These are perfect to secure your under-mount sink, they will hold the sink in place, I used commercial grade glue to attach them to the granite

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.

Ok

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