This black Explorer Cases 9433 Wheeled Hard Utility Case is designed to protect delicate equipment during transport and handling. A large carry handle provides easy handling, even when wearing gloves, and is covered in rubber for comfort under heavy loads, or you can grab one of the side handles and pull it behind you on the smooth-rolling wheels. The case is made from a copolymer polypropylene for resistance to impacts, temperature, and corrosion while an O-ring seal on the lid makes it dust and waterproof. The 9433 case is offered here empty, without an insert, to give you full access to the interior space.
