Engineered plastic side clips allow for stackability with other boxes. When carrying the toolboxes by hand, they can also be fastened together, allowing them to be carried as a stack. Heavy-duty metal latches and hinges provide added durability. The bi-material comfortable top handle is easy to grip, and locking side handles offer alternative lifting and easier maneuverability. Durable 4mm PP structural foam plastic ensures high impact protection. It is IP65 rated, meaning it is dust-tight and water jet resistant due to a high-performance seal in the lid. A pressure relief valve enables equalization of pressure inside and outside the unit. Padlock eyes provide lockable security.
