how much tension do spring hinges have?
I'm looking for hinges that will keep 20x30 inch panels shut tightly. The panels will be installed behind attic louvers and opened by pulling and tying off a cord. I need them to stay closed against a breeze or they won't do any good.
I'm aware that self closing door style spring hinges have a tension adjustment but I'm not sure how much tension they can provide. Could someone give me an idea of load? for instance if I had my finger between the two sides of the hinge would it feel like it was clamping down pretty well?
thanks!

The 'tension' required is a matter of leverage.
That spring is meant to close about a 30" door.
That's a 30" lever. At 1 " or so there should be a LOT of pressure.
If you're comfortable with your finger in the short gap you speak of,
the tension is too light.

I would put an uncooked hotdog between the louvers for 5 to 10 minutes and see if the dog yelps.
