CPT-4 Undermount Sink Supports Brackets Adjustable Stainless Steel Installation Kit for Heavy Duty Undermount Kitchen Sink (28-39.4 inches（71-100cm）)

Great quality product and I found it easy to install.

Worked very well to hold up an heavy apron farmhouse sink. Super easy to install.

I used these for my farmhouse sink and they work great. Easy to install and it leaves your cabinet open and doesn’t take up room. Would definitely recommend worth the money

The support is easy to install and strong. They are a little pricey but worth it

So far it's holding my very heavy ceremic sink. My father installed it. IF your sink is already there you won't encounter the same issue we did. Just hard to do due to lack of space. My father had to do it and measure first since we were placing the sink in. Instructions could be improved. He accounted for everything except for the wider side. So he had to redo it...and put more holes in the cabinet. He didn't like the screws that came with so he used bolts and modified it a bit. It's a great idea to be able to level after install but it only went so far so your measurements still couldn't be to far off. I like that its clean looking and give me space I ordinarily would have lost if a traditional frame was used.

We recently had to remodel our kitchen and used these supports to undermount a heavy large fireclay sink. The brackets are adjustable which was handy as the sink was not perfectly square.Be sure to leave room to adjust the sink up and down.

Bent under the weight of the sink, and did not support it at all. They advertise being rated for up to 800 lbs. Our sink was about 200, and they were nowhere close to being able to support it. Would give 0 stars if I could.

I used this to support a farm sink in my new cabinet. It's strong, easy to use, and looks nice under the sink.
