Your cart is empty.Install Sprocket onto door shaft with key and set screws. Install the main unit to the wall so that the roller chain will be free of slack when installation is complete (shorten roller chain if needed). If not already completed during the previous step, install the roller chain between the main unit and sprocket on the door shaft (move the sprocket on the door shaft if necessary to ensure the sprockets are aligned).

Not sure why they advertise it the way they do. I purchased two, and they showed up looking like “others” and not fully assembled.
