Construction
The entire filing cabinet has a double wall construction with a fire resisting compound in-between. The sheet metal thickness has been maintained to a minimum to minimize the condition of heat and has been substantially reinforced at vital places to withstand impact. Each drawer is housed in separate fire resisting compartments.
Poured cement insulating material forms a monolithic barrier and does not powder, flake or break.
The tongue and groove construction between the door and the body jambs prevent the passage of hot gases and flames into the drawer.
Drawers roll-out fully, freely and quietly. In an emergency a mere push will close an open drawer and secure automatically.

Locking
A 6 level dual control key lock on the top drawer controls all drawers. However, individual drawer latches allow the users to leave one or more drawers unlocked with the plunger in the lock position.
