How well do flat-file cabinets protect documents from dust?

Flat-file cabinet drawers, when closed, provide good protection from airborne dust. The drawer-to-frame tolerance is tight enough to exclude most particulate in normal office environments. For particularly dusty environments (print shops, construction sites), consider placing a sheet of acid-free tissue over the top of each document stack before closing the drawer. When locked, the cabinet provides excellent protection against casual dust infiltration. OfficeFurniture2go.com — call 1-800-460-0858.
