The Element 6104 Wheeled Utility Case from DCB Cases is made from TSU-1 resin and fiberglass-reinforced, injection-molded plastic for impact resistance. Independent latches with stainless steel hinge pins keep the case securely closed, and the rubber O-ring seal keeps water and dust out. The automatic pressure valve ensures the case remains easy to open even after air travel. The latches accept user-supplied padlocks for additional security. This durable and versatile case features a retractable handle and a pair of rugged wheels for easy transport.
