Stillage
A stillage is like a pallet or skid but with a cage or sides or some form of support specifically tailored to the material it is intended to carry. Some are designed to be stackable.
Stillages are mainly used to transport goods without the need to load and unload the product being carried, which saves time and decreases the chance of damage. An example is the use of stillages in the glass industry, where they are shaped like an upright "A"; the glass leans inward and is strapped to the stillage ready for transport.
