A. Sturdy and durable: The wooden shelf brackets are made of solid galvanized and nickel-plated steel and treated with a matte black powder coating. These shelf wall brackets are less likely to rust or bend, which helps ensure a relatively long service life. Although they are small metal shelf brackets, they are quite strong and can support shelves weighing up to 80 pounds. B. Invisible and hidden: The hidden shelf brackets are designed to be installed inside the wall and the shelf. After assembly, the hidden shelf brackets may not be visible. Since there are no brackets on the outside, the cabinets are easier to clean. C. Easy to install: If you want to hide the small brackets in the wood, use a 0.5 - inch milling cutter bit to drill a 5 - inch - long hole in the wooden board. It is advisable to make sure the thickness of your wooden board exceeds 0.8 inches. Fix the floating shelf brackets through the two screw holes and the holes in the wooden floating shelf, and then install the shelf on the wall. D. Space - saving: If you use these decorative shelf brackets, you may save more space because there are no supports on the outside. Therefore, you can install multiple shelves nearby. E. Wide application: These scaffolding board brackets perform well. The decorative shelf brackets are suitable for supporting your floating shelves. The shelf brackets can make your shelf furniture look beautiful and fashionable.
