Abstract
A locking system for a rolling shutter having a plurality of shutter slats and a guide track with a U-shaped guide channel having a channel base, comprises a lock bar coupled to the shutter slats with a locked position extending transverse to the channel base. A lock bar notch covered by a breakaway wall is aligned with the channel base in the locked position. The lock bar may be slidably received in a sleeve that is positioned in the guide channel to increase resistance to torsional forces. Alternatively, the locking system comprises a unitary extruded body with a longitudinal channel, and a lock bar, and handle received in the channel. The lock bar is slidable in the channel between an extended locked position and a retracted unlocked position, with the handle positioned in the channel to stop the retraction of the lock bar at the unlocked position.
