Abstract
A building closure operator includes an operator arm pivotable about an arm axis from an arm closed position to an arm open position, an arm lock actuatable to lock the arm in different locked positions and releasable to release the arm, and an articulatable lever pivotable about a lever axis parallel to the arm axis, from a lever home position corresponding to the arm closed position, to a lever actuated position corresponding to the arm open position. The lever includes a lever coupling maintainable in the lever actuated position, and a lever handle pivotable with respect to the lever coupling back to the home position to actuate the arm lock to lock the arm in one of the different locked positions.
