Janus International introduced MASS, a line of Movable Additional Storage Structures. The structures are built on a 10-by-20-foot platform and can be configured in a variety of unit sizes to offer self-storage managers an economical means of adding more storage space. MASS units are constructed of standard self-storage building materials and use full-size, 26-gauge roll-up doors. Units are movable with a 5,000-pound capacity forklift and can be pre-built or constructed onsite. Info: www.janusintl.com
