Stillage comprising similar containers in vertical stacked apart relationship to one another. The container includes a flat load carrying surface for carrying items and corner fittings having a collar for cooperatively engaging with one end of support legs to support the container. The support leg has an external plug provided with a pocket having this spaced side walls at one end and an internal cavity surrounded by an enlarged flange at the other end. The lower end of a spacer for spacing apart two containers is received in the pocket of the support and the other end of the spacer is received within the internal cavity of the support leg which is provided with a guide for guiding movement of the spacer to adopt and maintain the correct vertical orientation to form a stable array of vertically stacked containers. The advantage of the stillage formed using the support leg and spacer is that a stable stacked array is formed enabling safe transport of items in the containers without risk of damage to the items.
