The TRINITY 15-Inch Metal Hanging Basket to Use With Shelf Units and Storage Racks are very sturdy and useful storage baskets. I had originally gotten these to install on the ends of industrial shelving in my shop but, decided they would be more useful in the storage shed for holding lawn equipment supplies. This keeps items neatly stored and is much more efficient time and effort wise. I keep items like oil bottles, fuel stabilizer, chainsaw chains, etc... in the baskets. These are made of sturdy steel with a durable black painted finish. They are extremely convenient and space efficient and I consider them an exceptionally good value!
