Abstract
A locking bar assembly having a secondary safety release mechanism that includes a shaft that is removably engaged with and coupled to a strike plate cover of the locking bar assembly. The strike plate cover rigidly engages and secures in position a strike plate of the locking bar assembly. When the safety release mechanism is operated, the shaft is rotated to disengage and decouple from the strike plate cover thereby releasing the strike plate of the locking bar assembly and releasing the locking bar assembly.
