HPUFKOT Kitchen Faucet with Pull Down Sprayer Multitask Mode Single Handle High Arc Pull Out Kitchen Sink Faucet Offers Efficient Cleaning for RV, Undermount Sink Clips

Unfortunately, the original installer didn't place any supports in the center of our sink during the installation even though I questioned him about it. He cited that it wasn't necessary and in hindsight I probably should have insisted. In any event, at some point over the last 3 years I filled multiple 5 gallon buckets inside the sink which resulted in the center of the sink pulling away from the quartz counter top. Lesson learned as I now place the buckets on the counter top itself and fill them there. This lead me to here and my purchase of EZ Sink Clips along with the PC-7 Epoxy. It was simply a matter of scraping away the old silicone between the sink and counter and laying a fresh bead. I held the sink in place with a scissor jack and cleaned up the under counter sink area to mount the Sink Clips and marked their placement. Mixed the epoxy 1:1 (equal parts) and stuck them into place while waiting 48 hours before actually installing the support bracket and wing nuts and eventually lowering the sink onto the supports (removed the scissor jack). I should mention that the original installers actually made cuts in the counter top to installer their own support brackets on the corners/ends. I can only assume this type of bracket is used to save time on the day of installing as ideally you probably don't want to cut the stone. It also seems the orientation of the bracket will depend on the type of sink and sink lip you have under the counter. There is no right or wrong way to use the bracket from what I could tell but whatever fits best for your situation. TIP: I used a plastic knife to spread out the epoxy so it wasn't heaping on the base of the support after it squeezed through the holes. I also made sure to keep the epoxy off the threads so I didn't have issues placing the wing nuts on to the threads. The only oversight I made was placing one of the bases too close to the wood trip in the front of the sink and therefore was unable to use the original wing nut. Fortunately, I had a suitable nut/washer combo and therefore was able to use a socket/racket to secure it properly. It's been a week now and the sink has maintain it's position with no issues. The secret to this products success is really to use a lot of clips to spread out the weight/support of the sink across multiple points. I used the entire 10 EZ clips with 5 in the front and 5 in the rear to ensure there was enough support on each side.

Edit: 7 months later and it's still holding with no problem. I've loaded it with my Dutch oven and some cast irons a few times, as well as soaking some baking pans in it overnight. I really couldn't have asked for a better fix on my budget.Used JB Weld on a granite countertop to install these. I moved into a place that had decent second-hand countertops, but nothing to fasten sinks to the counter. The guy that lived there before me held them up with 2x4s nailed into the cabinets below the sink 🤦‍♂️At some point someone added silicone to it (He had them fastened *only* with the 2x4s) and it was a disaster.I took the sinks out, sanded them both, sanded the underside of the countertop, stuck some JB Weld on the bottom of these guys and a day later had myself a perfect sink. This was about 3 months ago now, and they've been holding well. I've soaked things in the sink overnight a few times since installation, and I've dropped my cast iron dutch oven in there on at least one occasion. At this point it feels safe to do anything I need to besides stand in the thing.I recommend keeping the wingnuts and metal piece attached to the bolts before installing the sink. It'll just make life that much easier.

I have bought this to mount my kitchen sink including the recommended epoxy )PC Products 167779 PC-7 Two-Part Heavy Duty Multipurpose Epoxy Adhesive Paste, 1 lb in Two Cans, Charcoal Gray ) , base clamp looks very thin hopefully ie good enough for kitchen sink. I have mixed the epoxy per directions , wiped and glued the clamp with the mixed epoxy. I have used all the 10 as I didnt want take any chances with the sink. Because directions says it needs 2-4 days to dry and until then sink should be supported from the bottom and I left it for 2-3 days even without connecting Garbage Disposal. After three days, started tightening the nut with the hand not using any tool . All of them look good with the hand tight except three which came loose as shown in the picture. So I had to go back to the granite installer and get their epoxy which was used initially and put some more using additional metals.Overall I liked the concept which is simple and straight forward but I was not hoping it would just come out with the Hand tight. It is almost 2-3 weeks and no issues so far :-)Wiping the surface is important and possible make it little rough by using sand paper .

I used it to hold an under mount kitchen sink
