Abstract: A device, system and method for preventing unwanted movement or shifting of drums or containers stored in groups of two or more. A core member is positioned intermediate, among or between the drums or containers and at least one pressure exerting member or strap is utilized to urge the drums or containers inwardly into direct abutment with the core member. The core member may be specifically configured such that the individual drums or containers will nest or seat firmly against the core member. The pressure-exerting member may comprise any suitable type of pressure-exerting apparatus or article including strap(s), band(s), plastic shrink wrapping, cable, chains, etc. . . . The core member may be formed in multiple segments or may be specifically configured to accommodate tapered, angled or odd shaped drums or containers having sidewalls which are not perfectly vertical.
