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 hole in the board. Ensure the board is at least 0.8 inches thick. Secure the floating shelf bracket using the two screw holes and attach it inside the wooden shelf, then mount the shelf securely to the wall. These space-saving shelf brackets allow for efficient use of space, as there are no external supports. This design enables multiple shelves to be installed close together. Ideal for supporting floating shelves, these shelf brackets enhance the appearance of shelving furniture, giving it a sleek and look. Suitable for various residential and commercial applications.
