For ages, people of all kinds have been repurposing milk crates in their homes, garages, shops, vans, trucks, and boats as well as on their bikes, ATVs and other rides. We took that crate and we made it modular, collapsible, strong and stackable. We also made it into a system by adding a number of attachments, accessories and sister products to use with it. It helps you store, carry and build.
