In larger class rooms or auditoriums the column board is an ideal solution. This board, combines two or more independently operating boards and a durable ceramic steel writing surface, offering an optimal writing surface. Both instructors and students work at the correct ergonomic height. As an option, different patterns can be applied to the board, such as squares or lines. The frame has an integrated pen tray which also provides an ergonomic grip so the board can be easily adjusted in the wanted position.
