Power-Assisted Doors and Gates [§404.3]
Power-assisted devices reduce the opening force of doors with closing mechanisms.
They are activated by initial manual force, switches, or sensors. Most reduce, but do
not fully eliminate, the manual force needed to open a door. For this reason, they must
meet maneuvering clearance requirements.
