Abstract:

A knock-down transparent module includes a module frame with a pair of vertical side frame members, each having an upper end and a lower end. Upper and lower horizontal frame members have opposite ends and extend generally horizontally between the vertical side frame members adjacent the upper and lower ends thereof and interconnect the same adjacent the upper and lower ends to define a central opening through the module frame. A transparent sheet is secured to the module frame and extends across the central opening. The module frame defines outer faces having at least one hook shaped to engage an opening in a partition frame member, thereby permitting the module frame to be removably supported within a partition.
