Vance Industries QN23UM 23" Universal Undermount Sink Installation Kit,Silver

I got carried away and got the largest sink that "fit" my cabinet. Unfortunately, I didn't realize it until my quartz countertops were cut and delivered already. This was the only way I was going to be able to securely undermount the sink. While it was completely my fault, there wasn't enough room on any side of the sink to use the clips included with my sink or countertop install kit.I did have to cut the braces to fit the depth of my cabinet, and it took a couple of tries to get the saddles aligned. I didn't like that the saddles rest on the top edge of the cabinet and are sandwiched between the cabinet edge and the countertop. Because of that, I had to use some shims to support one side of the countertop, and it's no longer perfectly level.I do have two warnings for other first-time users. First, make sure you have a long enough driver to reach the bolts. I ended up having to use a 6-inch Phillips bit in a 6-inch bit extender on a manual bit driver to reach it. Second, when you're tightening the bolts to squeeze the sink edge to the countertop, DO NOT OVERTIGHTEN! This system is mounted to the cabinet, so overtightening will raise the entire countertop.This thing is strong; I have no concerns that the sink is going to fall. It was the only solution I could find that got me out of the pickle I put myself into, and it arrived within 24 hours. It wasn't as easy to use as I had thought, but it's still a great product.

I’ve used multiple techniques to install under mount sinks and this was by far the easiest. Very confident this will hold up for a long time!

it gets the job done

We got duped by a contractor that glued our sink to the stone countertop instead of installing it properly. So of course after a few years, the sink started to droop, then finally detach. These metal brackets are installed on the top edge of the cabinet, to support the sink. There are attached bolts to adjust the sink height, to line it up with the countertop. Caulk, then voila, your sink is firmly supported and will never droop again.Obviously will only work if you have a cabinet or other vertical support system below your sink to attach the brackets to.Would’ve been nice if they were curved, to offer more contact for support, but I guess then they wouldn’t be as universal.

These were too long for our 21” depth vanity cabinet. Cut to proper length with a metal saw and installation was then simple. Granite template and installation people were happy to have these to work with as the leveling of the sinks was simple and resulted in a secure installation. Never again mess with trying to secure an under mount sink any other way.

This worked GREAT and the adjustability should fit any needs. The previous owner had installed our granite tops with some scrap lumber from another job and bondo and liquid nails.Please ignore the reviews that say these may be too wide. It clearly says in the instructions that you can trim the brackets. I used them inside a 23” cabinet and the distance between mounting surfaces was only 22” so I trimmed with a sawzall.

Works as intended once installed, but problem is that square inserts/nuts are a bit too small and start twist vertically and rotate once you reach the sink with a bolt. They must be wider to sit snugly within the channels. Due to this what could be a breeze install took me a good hour of lying on my back under the sink.Otherwise, the product is very helpful and metal is solid.

The Kohler cast iron sink weighed over 100 pounds and this bracket held it up just fine.
