This HON 600 Series Three-Drawer Lateral File comes with a counterweight included, where applicable, to meet ANSI/BIFMA stability requirements. It also features a "One Key" interchangeable core removable lock that secures both sides of drawer and a heavy-duty, three-part, telescoping, steel ball bearing suspension for smooth drawer operation. The mechanical interlock of this modern file cabinet allows only one drawer to be open at a time to inhibit tipping while four adjustable leveling glides help compensate for uneven flooring. The drawers come with side-to-side hang rails for letter or legal size filing and bright, anodized aluminum recessed drawer pulls with magnetic label holders.
