ABSTRACT:
A security bar that can be retrofitted onto a gate used in a typical fence construction to prevent unauthorized tampering with or opening of the gate. The device includes a rigid locking bar that is firmly mounted to the gate, a T-shaped strike plate, and a key-actuated latchbolt mechanism mounted within the inside of the rigid locking bar so that the latchbolt and strike plate cannot be accessed for tampering. The strike plate is mounted to a conventional fence post with fasteners that are not accessible when the gate is closed. Using the present device, which can be retrofitted to any type of outdoor gate, a positive locking action insures that the gate is locked at all times and cannot be jimmied or pulled upward to a position that would allow it to be opened. The locking mechanism allows access from either side of the gate for actuation.
