Details: 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. Insulation between all drawers makes each drawer a separate insulated container. Water-resistant file is also designed to prevent water damage from sprinklers and fire hoses. Scratch-resistant finish is an environmentally friendly electrostatic powder coating applied to all sides. High sides are ready for use with hanging folders so no additional frames are needed. Locking drawers operate on full-extension, ball-bearing slides. Highly secure, four-drawer file also features recessed handles, field-replaceable steel panels and a UL-listed, high-security, Medeco key lock. Two-position drawer catch allows access to one drawer while the others remain locked.
