Sturdy and durable wood shelf brackets are made of solid galvanized and nickel-coated steel with a matte black powder coat finish. These wall shelf brackets resist rust and bending, ensuring a long service life. Despite their compact size, these metal shelf brackets are strong and can support shelves weighing up to 80 pounds. Hidden shelf brackets are designed to fit inside the wall and within the shelf. Once installed, the brackets are not visible. With no external brackets, the shelf is easy to clean and maintain. To install, use a 0.5-inch router bit to cut a 5-inch-long mortise in the wood. Ensure the shelf material is at least 0.8 inches thick. Secure the floating shelf brackets using the two pre-drilled screw holes in the bracket and attach the shelf to the wall. These space-saving shelf brackets allow for closer placement of multiple shelves since there are no external supports. The clean, minimalist design enhances any room. Ideal for supporting floating shelves, these decorative shelf brackets provide both functionality and style. They help create attractive, modern shelving furniture with a sleek appearance.
