Our countertop support brackets are meticulously crafted from premium iron, effectively supporting heavy loads. In addition to utilizing thick steel, the two steel plates are securely welded together. Each pair of brackets can bear a weight of approximately 100 to 200 lbs. making them an ideal choice for maximizing wall space and enhancing storage capacity. The floating wall-mounted brackets are not only economical but also provide effective countertop support. The horizontal support measures 2 1/2 in. width, 3/8 in. thickness, and 12 in. length; the vertical mounting flange is equally 2 1/2 in. wide, 12 in. long, and 3/8 in. thick. Installation is simple and quick, requiring only the measurement and marking of appropriate mounting locations on the wall, using a chalk line or laser level to mark a straight line, securely attaching the bracket to the side of the stud, and finally filling in any wall gaps. Before placing the countertop, apply a bead of high-quality silicone adhesive down the center of each bracket. Floating wall-mounted brackets have a wide range of applications in daily life, with one vertical side fixed to the wall stud and the other side extending out to support wooden workshops or granite countertops. They are perfect for floating support needs such as floating desks, benches, workshops, vanities, or countertops made of quartz, granite, wood, concrete, and laminate. Color: Black.
