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 long-lasting performance. Despite their compact size, these metal shelf brackets provide strong support, capable of holding shelves up to 80 pounds. Hidden shelf brackets are designed to fit inside both the wall and the shelf. Once installed, the brackets are not visible, creating a clean, seamless look. With no external brackets, the shelf surface is easy to clean and maintain. To install, use a 0.5-inch router bit to cut a 5-inch-long mortise in the back of the shelf. Ensure the shelf material is at least 0.8 inches thick. Secure the floating shelf bracket using the two pre-drilled screw holes that connect the bracket to the wall and shelf, providing stable wall mounting. These space-saving shelf brackets eliminate the need for external supports, allowing closer placement of multiple shelves and maximizing usable space. Ideal for supporting floating shelves, these decorative shelf brackets enhance the appearance of shelving furniture, offering a sleek and modern look suitable for various home and office applications.
