4-shelf System (Side-by-side Type)
When vertical space is limited, it is possible to install a fully expanded system (Basic Shelf + Expansion Shelf
1, and Expansion Shelf 2 + Expansion Shelf 3 ) in a side-by-side configuration. Expansion Shelf 1 is mounted
on the Basic Shelf, and Expansion Shelf 3 is mounted on Expansion Shelf 2. Installing the system using base
stands (supplied with an optional Mounting Kit) makes it easy to reinstall shelves in a different place.
