Review on Maximizing Space with 4Pc Storage Boltless Shelving Capacity: Organize and Store Efficiently by Deborah Lewis

These casters have breathed new life into my old premium Gorilla Rack shelving. I've been able to convert my shelves into rolling shelves, which makes it a lot easier to get a tool shelf to a work piece or move the shelf away from the walls to mop the floors. I think I bought 1 set and was so in love I bought 4 more. I even converted one of my Gorilla Racks into a rolling wood storage rack. It's amazing how much more useful shelves are when you can access both sides of the shelves. Big fan. Highly recommended.
