1. Plastic tool boxes are light, durable, and non-corrosive. They clean easily with soap and water. Transparent plastic makes for quick tool identification. Black plastic is scratch resistant and ideal for truck beds.
2. Plastic tool boxes with wheels are perfect for outdoor use and save treks to the workshop. Wheels are recommended for large tool boxes and tool chests with heavy tools or those with shoulder or back problems.
3. For storing tools in your vehicle, you can find plastic wheel well tool boxes that attach to the side of the truck bed and over the wheel well; you'll also find truck bed tool boxes to stretch across the back of a pickup cab. Car accessory manufacturers also sell under seat storage tool boxes for cars and vans.
