How it Works: As you can see in the picture, our products do not need wire decking. This product does not contain any wooden boards, the customer needs to buy it separately, this product only needs you to install it on the ceiling correctly and we have a complete installation instruction. When you finish the installation you will find it is a perfect storage solution. Heavy Duty:Our product is made of high strength steel 3/32 inch thick. This steel has an irregular shape, ensuring that it can be worked by a heavy duty performance. A strong coating does not corrode easily. Safety and heavy duty products are provided for your garage. The six-leg design guarantees about 1,000 pounds of carrying capacity. In addition, we use high-strength hexagon head pull screws. Our screw size is 5/16 "x3". Benefits: Wire decking is inconvenient when moving small items or boxes, which is why we give it up. Wood boards don't have this problem and they are affordable. Our product has many holes in it and its size can be adjusted from 4’x4’ to 4’x8’. So you can adjust the size to create your own storage space. We have provided the complete instruction and all the accessories. It is simple, efficient and now the most affordable ceiling rack on the market. WARNING: Although my product has a capacity of about 1,000 pounds, but you need to make sure that your garage ceiling has capacity for 1,000 pounds. In addition, the hexagonal head pull screws must be installed on the structural parts of the garage ceiling, and ensure that the structural parts can hold up to 1000 pounds or you risk serious damage to your home, life and personal property.WOOD BOARD IS NOT INCLUDED IN THIS SET.
