The SKB 3i-4U11-W combines the durability of injection molded construction with genuine portability for touring sound engineers, live production teams, and systems integrators who need to travel with rack-mounted equipment. The 4U capacity accommodates power amplifiers, digital processors, control interfaces, and other rack modules—all protected during transport and accessible through front and rear rails for field connections.

Built for compliance with airline carry-on standards, this case features TSA-accessible locking latches that let security personnel inspect contents without compromising your locks, reducing airport delays and equipment risk. Gasket-sealed doors keep dust and moisture out during transport, while the molded-in protective lip guards the rack structure from impact and environmental exposure. Integrated wheels and a telescoping pull handle eliminate the need for separate hand trucks, making equipment deployment faster on concrete venues, outdoor festivals, and remote broadcast locations.
