A non-handed panic bar mechanism for an exit door having a frame with a stile, upper and lower lock rods for vertically sliding in the stile, and a lock rod drive mechanism with a drive pin projecting outward from the stile for up and down movement, with movement of the pin driving the upper and lower lock rods in opposite directions. The mechanism further includes a base for mounting on an exit door, a presser bar carried on the base by a compression mechanism for movement toward and away from the base, a push rod carried on the base for motion along the axis of the rod, a lever pivotally mounted on the base and having a slot for receiving the drive pin externally of the stile, and a link connected between the push rod and the lever for pivoting the lever to move the lock rods when the presser bar is pressed toward the base to translate the push rod along its axis. |
