Countertop Support Brackets, Heavy Duty L Shelf Bracket 16'' x 6'' x2.5'' for Granite, Holds up to 300 lbs, L Bracket for Quartz, Granite, Wood, Concrete and Laminate Countertops(2 Pack)

Very heavy and well made. The holes are countersunk for the screws to fit completely flat. They are finished nicely with a powder coated texture and are exactly what I needed to make sure that my marble top overhang will never be cracked or broken. You could park a truck on these things!

I decided to use these under my small bar seating in my kitchen, i mounted these under a quartz countertop. The mounts came with 3 black screws for the top, and 3 longer black screws for the bottom. The flat matte black color really popped against my white counter, and white wall. Seems to stop the flex i was getting when people leaned on the counter, so seems to have strong support. Seems very durable and good quality.

Bought these to build a “floating desk” - very sturdy product!

Got these for a kitchen remodel, worked great, heavy duty.

These are top quality. Thick as expect and performed perfectly when put in place. The value and the look are exactly what I hoped for.

Solid, thick, indestructible slabs of bent steel plate with beveled forks. Beautiful and strong. Exactly what I needed.

Installed on wall to hold a 1” thick 40”x20” solid marble free standing counter for breakfast nook or buffet! Excellent! Well made,

these are some heavy duty braces. used under granite for support
