This invention is directed toward a wheel assembly that can easily be attached and detached from a case—specifically in a preferred embodiment an SKB 3i series case—such that the case can be wheeled when needed, but have the wheels removed for storage or transportation in a vehicle or plane. The wheel assembly comes in three parts—an axel, two wheels, and two wheel mounts—so it is simple to assembly, and because it has no moving parts, it is solid and durable.
