Mark, What would happen if the canopy door is open and a gust of wind hits it? Will it still hold? Considering the door is hinged (almost all doors are) the force acting on the spring while closing is not parallel to the axis of the spring. Chances are that the inward (towards the hinge) or outward (away from the hinge) component of the force exerted by the wind will push the spring in one of the directions and the door will fall. The question is how much wind force? It can be calculated by analyzing your setup, weight of the door etc...
This is my opinion and just that. Am I missing something? (I must be.)
