The instructions for the Conventional Ramp Door Spring # M374FR state to wind the spring 38 quarter turns or 9-1/2 full turns. At this point you will want to test the door operation and make 1/4 turn adjustments adding tension or removing tension to balance the door.

The door should be open when winding the springs.
