Definition
The red-handled cord hanging from the opener trolley that disconnects the door from the motor, letting you lift it by hand during a power outage or opener failure. Two safety notes: only pull it with the door fully closed if possible — a disconnected door with a broken spring can fall — and know that the door will be dead weight, so lift with care. To reconnect on most openers, pull the cord toward the door and run the opener until the trolley clicks back in.
