ABOUT GROUND LOCK

At JMR Earl, Inc. we have developed the Ground Lock in response to the most daunting security challenge of the twenty-first century, aviation security.

  • Ground Lock isolates the main aircraft battery from the electrical system thereby rendering aircraft incapable of operation.
  • Ground Lock connects to military-standard type quick disconnects regardless of manufacturer.
  • Ground Lock is easy to use. View: Operation Instructions
  • Ground Lock lock components are custom manufactured by Medeco® a leader in the high security lock industry. Connector interface components are precision machined from tool steel and heat treated for durability. The lock assembly is encapsulated in a Delrin™ insulator for electrical safety.
  • Ground Locks can be keyed alike when multiple locks are purchased.
  • Ground Lock can be custom pinned to match your Medeco® aircraft locks.
  • Ground Lock serial numbers and key codes are registered with JMR Earl, Inc. for optimum security.
Ground Lock is billed at $350.00 per lock and includes two keys. For security purposes, Ground Locks pinned to existing Medeco®  aircraft locks do not include keys. Shipping and handling are additional. Applicable sales tax will be incurred on purchases.
