We commit to design a kind of rack which can be installed with no tool and serve as a practical storage shelf to enlarge your storage space. The boards and tubes of the rack are made of thick and solid plastic, which is sturdy and not easy to deform. It can stand firmly on the floor and provide large weight capacity. For indoor using, the rack can be placed in kitchen, study room, garage and office for some tools, cookers, boxes and office supplies. With waterproof surface, the rack is suitable to be used outdoors for plants and some garden supplies. You can choose how many layers you need according to the height of place. And equipped with tilting preventing devices, the rack will not fall forward because of fixing against the wall.
