Teachers have a lot in store for their students. And a lot to stow away when the lesson plans change. With this SmartLink 52-3/4"W storage cabinet, materials can be easily rolled around wherever the activities demand, then stored and scooted out of the way when the time comes. Three 12"W columns with seven pairs of rails each help organize all sorts of items and support optional storage accessories like trays and shelves. The hard surface casters help teachers and classrooms stay in constant motion, just like the students.
