It will be easier to balance the door if the spring is wound in quarter turns.
Please note that we highly recommend only installing this if you have had previous... view full answer...

When wound properly the 120 lb lifting force of the Conventional Ramp Door Spring # 362SA6 is going to be basically throughout the entire range of the ramp being lifted as you'll feel it. That said, the spring will be helping the most when the ramp is on the ground and as it gets closer to the being closed gravity will affect it less and less which works out perfectly as the pulling force of the spring will begin to diminish at the same time.
