I installed them and they do work well. Might help in the event of a slammed-down canopy, but what really works there is *any* kind of gust lock. I use a piece of stiff Parker Parflex hose, slit lengthwise, and slipped over the extender on the lifts. And I am *religious* about putting it in *any* time the canopy is up.
Good luck with the repair...let us know how it works out.
