Light duty Boltless Shelving is different from many shelves that require bolts connection. Beams are hooked onto uprights from inside. If you see from the front, it is very beautiful and neat without any bolts or nuts shown. We put such storage racks in stores, kitchens, and study rooms. They are beautifully decorated shelves. The surface is treated with a very textured special process, which is not only beautiful but also very durable.Light-duty Shelving Free Sample website:http://www.goohorack.com/light-duty-shelving/
