Large shelf for wood. Includes true 3" lag bolts. This set is cheaper than another from kastforce and more customizable where the support beams go. More importantly, the support beams are adjustable to a degree and can be raised, held in place by a pin. I don't expect to have to raise the bars vertically, but it's fine if needed. Also, the logs are a few inches longer than the Kastforce, meaning more wood can be stacked on top. And it's cheaper than other comparable ones! Cons: no instructions. Nothing, but look at the pictures on Amazon and you will quickly understand everything. I was missing a pin, which means one can go through to the last ray. So the quality control might be a little lacking, but I can easily get them at my local big store. If I saw this brand for the first time I would make all my shelves with this brand. I'm deducting a star for the lack of a pin.
