Vertical file provides your important records with the protection they need. The 25" deep, four-drawer vertical file with recessed handles offers the same Class 350 one-hour fire and impact rating as the standard unit size. Fireproof insulation is 100 percent gypsum, reinforced by a 1" x 2" lattice made of 14-gauge, galvanized, welded steel wire, providing complete peace of mind from fire, impact, or explosion. Two-position drawer catch allows access to one drawer while the others remain locked. Drawer heads are formed of welded steel. Scratch-resistant finish is an environmentally friendly, electrostatic powder coating applied to all sides. High sides are ready for use with letter-size and legal-size hanging folders so no additional frames are needed.
