A few weeks ago I cracked my bathroom sink and bought an American Standard to replace it. The American Standard came with clips that required drilling into the bottom of the granite (lots more work than I thought it would be, even with a mason bit) and securing a threaded insert into the hole using epoxy. One this was set, the theory was that you could put a screw through the clip and screw it down to the threaded insert. The threaded insert was only a little bigger than the screw itself and when I tried to tighten the screws the insert would spin and the epoxy would fail.I tried 3 different types of epoxy, cleaning with a brush and acetone each time. After 3-5 tries I started to think about how a plate that could be glued to the underside of the countertop would have more surface area to grip than the small threaded insert and would be less likely to spin when tightening the screw. I came on Amazon to look for parts to build what I was thinking and found these - pretty much what I was envisioning. Even better, holes in the plate would allow epoxy through and great stubs that would further keep the plate from spinning.I have literally been trying to get the clips that came with the sink to work for 2 weeks, so for less than $15 I had nothing to lose. I bought a pack and some PC-7 epoxy based on the reviews on here.Installing these was so fast in comparison to the other clips. It took me over an hour to drill 4 small holes in the granite with the other clips, and that was before I even got started on the clips themselves.These clips arrived and it took me 15 minutes to epoxy them to the countertop. I let the epoxy cure for 36 hours (PC-7 says 24 hours but I wanted to be sure).When I checked today the clips were very secure and I could tighten the screws down nice and tight with no hint of the anchors spinning or moving. I wish I had purchased these when I got the sink. The install was easy and fast - and I am confident they will hold better than the clips on my hold sink.

Update 3/27/24: While my handyman was finally adding the additional brackets I mentioned in my initial review a couple of months ago, I found that at least one of the wing nuts on the clips had come completely loose. My handyman wondered why, and I pointed to the garbage disposal unit attached to the sink. My handyman will put blue threadlocker on the nuts as soon as I pick up some new. You might consider doing the same. Also, I finally computed the weight of the water in the two sink basins supported by the ten disks in the test in my initial review, and it was about 133 lb. Since this is more than my weight, it seems that at least I could already stand on the sink without the additional brackets. But of course you cannot be safe enough.My handyman glued those below my quartz counter top, using PC-7 epoxy, to keep up my stainless steel kitchen sink. He told me the intention is that the glue oozes through the holes in the disks. Anyway, after letting them cure for a couple of days, I filled both deep basins completely with water, and not a murmur from the clips, and no problems three months later either. Even so, I have also ordered undermount sink brackets. I just dislike depending completely on glue, and what if some idiot stands on the sink while doing something with the kitchen window? You cannot be safe enough.

Easy to apply. Durable.

Well this is a job still in progress. I glued these anchors to the bottom of a under mount counter with Gorilla construction grade cement in the tube,The anchors come ten to the count, and are sturdy as heck. HOWEVER, this new sink made by Kohler is one heavy son of a gun. So here’s how I installed the sink, I went and bought a 3/8 all thread rod four washers and four busts took and cut a 2x4 one piece about 5 inches long drilled a hole 3/8 bit through the center and a piece of 2x4 about 24 inches long and drilled it in the center of the board 3/8 , ran the all thread through the 24 inch board through the drain hole of the sick the washers one slightly larger than the other then the larger washer then the nut. On the bottom I placed the five inch piece of 2x4 and the two washers and nut delicately ran up the threads till the sick was almost in contact with the counter then put a generous amount of Gorilla construction grade cement on the edge of the sink and cinched it into place slowly and once I was happy with the position all the way around the circumference of bothe the sink and the counter I walked away and let the cement do it thing and dry. The next morning I went back with Gorilla 100% white silicone and ran a bead completely around the rim to seal the sink and counter just run your finger around the bead to get it into the crevice and every 4 inches or so wipe your finger off of the excess Caulk and continue running your finger along the crevice repeat this till you reach the spot you began. Check your bead for a good seam and clean any silicone you may have missed, Not the boards ar still in place and I haven’t loosed the nuts that would leave the sink to be locked in place by these heavy duty clips. I moved on to another project in the same bathroom, now it’s been about two weeks now and Im confident the clamps will hold the weight, it’s the marble counter that I hope will hold the cement and stay bonded to the clips . All that’s left now is to loosen up the top nut and let the full weight of the sink rest on the clips let that position set for a while before I drop the new drain and connect everything up to the P trap, on the side of caution if the cement doesn’t hold the clips no problem the bracing is still in position to stop the sink from falling out of position, so it’s really a wait and see now. But if all fails I will look at a nice copper hammered rustic drop in sink. But to finish up here I replaced everything under this sink new valves braided lines new faucets and new ASB drains. Painted the cabinet under there to. So with a little luck and a prayer the gorilla construction grade cement holds .Oh I have no doubts the clips will hold. You could run a tank over them there good to go..

These are the ones! Used an epoxy and these for an under mount sink and they held without a flaw! Highly recommend
