Bring order to your clutter with this 30-compartment literature sorter. Its 15,000-sheet capacity gives you a versatile solution to organize your large-scale document storage requirements. Heavy-duty plastic construction will not sag or bow and outlasts cardboard alternatives for long-lasting use for years to come. Integrated label holder on each compartment allows you to customize each space to prevent misfiling. If 30 compartments aren't enough, its stackable design lets you add extra sorters (sold separately) to create up to a 72-compartment unit. Each compartment measures 9-1/2" x 12" and holds up to 5 lb.
