The Nobo Steel Folding Confidential Whiteboard has 2 hinges and creates 5 dry erase writing surfaces. The painted steel whiteboard surface delivers a good level of erasability for moderate use. The case is lockable using Allen Keys only. There is no facility to use a key or combination lock, in the current design. The two outer panels fold into place over the central panel, hiding (if necessary) the content on the central panels and inside faces of the outer panels. The whiteboard measures 1200x900mm when closed.
