Sturdy and durable 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, providing a clean and seamless appearance. Without exposed hardware, the shelf is easy to clean and maintain. To install, use a 0.5-inch router bit to cut a 5-inch long mortise into the back of the shelf board. Ensure the board is at least 0.8 inches thick. Secure the floating shelf bracket using the two screw holes that align with the wall and the shelf. Once fastened, the shelf is firmly mounted. These space-saving shelf brackets allow for closer placement of multiple shelves since there are no external supports. This design maximizes usable space and creates a sleek, modern look. Ideal for supporting floating shelves, these shelf brackets enhance the appearance of shelving furniture, making them suitable for various home and office applications. The clean, minimalist design complements modern decor while providing reliable strength and stability.
