Does the Ramp Spring # RS16933LH Help Open or Close When being Used Trailer Door/Ramp
Question:
Is the spring designed to close or open as its placed under tension? And, does there need to be any space between the spring and the round bar its around....what if its a tight fit? Thanks!

Using your terminology, the spring closes as it is flexed when the door is lowering. The spring part # RS16933LH that you referenced is designed to apply torque to help lift a ramp door all the way up. If you check out the picture I attached you will see how it will look when installed with the ramp all the way up. As the ram would open the spring would flex which would apply torque on the door to make it feel lighter.
You want the ramp shaft the spring is installed on to be as tight as possible to it. The inner diameter is 1-1/2 inches so you would want to use a 1-1/2 inch diameter shaft.
