Shelf units make it easy for you to free up floor space and organize your tools and supplies. We have a large selection of freestanding models, plus add-on units to expand your shelving space when desired. Models are available in sturdy steel construction, along with corrosion-resistant plastic and stainless steel. Several shelf units have up to 10 shelves for additional storage space, while some even have shelves that can support very heavy items up to 2000 lb.
