Review: Sturdy, solid and nicely finished. - 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!
Review: Heavy Duty Support - 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.
