ABSTRACT:
A work board assembly having a board and hook assembly mountable to a rail assembly, and the rail assembly is mountable to a wall. A flip chart holder may optionally be hung on the board to add versatility to the board. The hook assembly is rotatable, thereby allowing opposite surfaces of the board to be easily and quickly exposed. The exposed surfaces may accept markers or the surfaces may allow tacking of documents, or one surface may be for markers and the other for tacking. The rail assembly includes a bracket designed to be attached to a wall and to mount a rotatable cam. The cam is received by a rail and rotation of the cam causes locking engagement of the rail to the bracket.
