Abstract
A slat for a rolling shutter comprises a body having a longitudinal channel and a side opening to the channel. A stop bar is slidably received in the body channel and is moveable between an extended position projecting from the body and a withdrawn position retracted toward the body. The stop bar comprises a rack that is actuatable through the side opening to move the stop bar between the extended and withdrawn positions. A pinion is positioned in the body channel in engagement with the rack, the rotation of the pinion actuating the rack to move the stop bar. The pinion is accessible for rotation through the side opening.
