Fort Knox Locking Device

High Security Ringless Meter Locking Device


The Fort Knox offers the highest level of security available for a ringless electric meter socket. Made of heavy duty carbon steel, the Fort Knox features the exclusive "Bolt-Down" mechanism which draws the meter cover down and establishes a secure metal-to-metal contact on even the most battered boxes. The fulcrum design successfully resists tampering attempts by evenly distributing the forces caused by prying attempts. The Fort Knox is available with a plastic sealing ferrule or the high security heavy duty steel sealing ferrule.
