Sink Clips, Undermount Sink Brackets, Bathroom Kitchen Ceramic Stainless Steel Sink Basin Support Clamps for Marble Granite Vanity Countertop Installation Repair Kit (10)

These worked well and easy to install. I used Loctite quick set epoxy to fasten them to cultured stone.

Worked great for a non drilling situation. Just be careful with the glue on the threads and a dripping through the holes when pushed. But definitely did the trick.

Brackets worked fine and I would make several suggestions in the process if you're mounting a sink from below the counter. First position sink without any adhesive/sealant and pencil mark outer rim edge; position desired bracket placement positions with pencil also during this time; use J-B weld either 1 minute or 5 minute silicone two-part epoxy (.85oz). I found that one epoxy pack provides enough for two brackets, but don't mix full contents at once: mix only for one bracket at a time - especially if using the 1 minute quick-set type. For the 5 minute set, take your time in mixing and regardless of which is used, don't apply paste if it will "run' off the applicator (use thin plastic 1"strips). And don't apply too much because when you press the circular piece in position, since you're working from below the counter, excess epoxy may run down the threads - on you, also - and harden. If that occurs, the paste will harden and will restrict proper, full tightening of the wing-nut to the metal bracket support against the rim. Do not attempt to tighten wing-nut until the circular piece has set for the duration - if you do, it is likely the wing-nut will encounter the wet epoxy and weld itself to the bracket --- not good for any future removal

I guess working upside down is always going to get messy, but this product could’ve done a better job helping with the install. Ultimately, once installed, it seems to be supporting the weight of my sink (of course there’s already epoxy between the sink and the countertop). But these give a sense of extra secure. But what a mess! The open slots allowed epoxy to drip everywhere and the product doesn’t provide any way to hold the clips in place while being installed.

Screwed these into the underside of a butcher block counter top for an under mount style sink. They seem very durable, easy to install and work great!

They seem to do what they were supposed to do

do the trick

I used epoxy to glue to bottom of counter top and provided pressure with clamps until glue hardened. I highly recommend when you are gluing the base, make sure to wrap tape around the threads of the bolt so glue does not get on them. I accidently got glue on the threads of one and could not get the bolt to thread on it.

Perfect for the job.

Very good product. I used cold weld to attach the clips to the underside of a quartz counter, the clips are great and it's a pleasure to work with. Shipping was a bit long, but did the job. Satisfied and I think this product is recommended to anyone!
