When choosing a sub-rack solution from Wakefield Thermal it is important to note what packaging components are suitable to work with each other. All guide rail types are compatible with all sub-rack systems. The Ripac Easy and the Ripac ECO sub-components are only compliant with their respective family of sub-rack. The only exception to this rule is that the Ripac Eco’s horizontal rails are compatible with other families of sub-racks. The sub-components on the Vario Systems such as, Ripac Vario, Variio EMC, and Vario Mobile can all be used for each other.
