Acoustical Portable Dividers help educators make MUCH better use of their facility's space, time, and money. *Easily create temporary or semi-permanent areas for classrooms, before/after school programs, tutoring, art shows, community events, and much more. * Tackable panels allow for the attractive display of artwork, bulletins, etc. * Self-leveling casters, full-length hinges and position controllers all help keep the divider standing straight even on uneven floors. Hence the USPTO's "Stabilized" divider designation and hard earned 4.9* Google Review rating from our customers.
