## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality
*by N***S on May 15, 2025*

Awesome ! Spaced them out 4’ (+\~) to supporta 10” overhang of a granite c-top and well supported. Braces are heavy duty , nice finish and come with screws to complete installation !👍🏻

### ⭐⭐⭐⭐⭐ Counter top extension
*by A***R on January 16, 2025*

I bought these for a countertop I was installing at my house. The metal is 3/8 thick and very heavy duty. These are well made, with what looks to be powder coating black as the finish. The brackets are pre-drilled and come with strong screws to anchor the bracket to the base. Recommend

### ⭐⭐⭐⭐⭐ Used for Kitchen Island Granite
*by Y***Z on May 23, 2024*

Purchased these for our kitchen island that will have a granite countertop overhang.The reason is they were relatively affordable and seemed easy to use. I used a skill saw to notch out 3/8" grooves and then took care of the rest with a oscillating tool. This created pockets for the bracket to sit in.I recommend offsetting the first and last bracket away from the edge of the countertop so that it is less visible when everything is completed. I would also suggest using drywall shims to fine tune the level of each bracket. This will ensure the countertop sits flat and doesn't have gaps anywhere. (this honestly is the more tedious part of this process)
