Conveniently store and systematize your daily essentials with the Luxor Double-Row Mobile Bin System. A steel frame and sturdy guide rails securely hold eight 6 inch polypropylene tubs that can each hold up to 20 lbs., making the unit ideal for organizing larger materials. A built-in safety feature prevents bins from unintentionally pulling out of the rack. The mix-and-match rack system also fits our 3 inch-deep tubs (sold separately). Four casters, two with locking brakes, make moving the unit easy even when fully loaded, yet stable when required. Its simple accessibility and durable design make this versatile storage cart great for garages, classrooms or industrial facilities.
