WFX Utility is 20 pounds heavier than the competition. That means it's truly heavy duty! At WFX Utility the focus is the quality of construction. Others are much flimsier and will not last. Item weight is everything if you want your shelving to last. Clean up your home or garage and get organized. This wire shelving gives any homeowner ample space to store and organizes their tools, storage bins, sports equipment and home goods. Constructed from high strength steel with industrial-strength zinc coating, these shelves can hold up to 500 lbs. 3" wheels allow the unit to be easily moved even when fully loaded. Shelves can be adjusted in 1" increments or removed entirely to allow space for larger items.
