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 capable of supporting shelves 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 look. Without exposed brackets, the shelf surface is easier to clean. For installation into wood, use a 0.5-inch router bit to drill a 5-inch-long hole into the board. Ensure the board is at least 0.8 inches thick. Secure the floating shelf brackets using the two screw holes and fit them into the wooden shelf, then mount the shelf securely to the wall. These space-saving brackets allow for efficient use of space since there are no external supports, enabling multiple shelves to be installed close together. Ideal for supporting floating shelves, these brackets offer reliable performance. They help create a sleek, modern appearance for your shelving furniture, enhancing the style of any room.
