Full-size vertical file provides protection for all your important files with a Class 350 one-hour fire and impact rating. 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. Scratch-resistant finish is an environmentally friendly, electrostatic powder coating applied to all sides. High sides are ready for use with letter-size hanging folders so no additional frames are needed. Locking drawers operate on full-extension, ball-bearing slides. Highly secure, two-drawer file also features recessed handles, field-replaceable steel panels and a standard locking system. Two-position drawer catch allows access to one drawer while the other remains locked.
