Help with High Lift Conversion

[P0234]

So I had my garage door converted from a traditional to a high lift. I guess one of the benefits of the traditional door opener vs that jack shaft was that it put a little bit of pressure in the middle of the door to snug it up against the door frame. The door is a cheap builder grade and after the conversion, when the wind blows, the middle of the door bows in and I see some daylight. This is probably going to be more of an issue as it gets into windy season.

Is there anything I can do to snug it up? I was thinking of maybe some kind of loop and a hook that catches as it comes down into its final position. To be clear the sides are good, its just the door bows in under some pressure.

Have you adjusted the top rollers to snug it up tighter to the wall?

Also, if your door significantly bows, you may need to add additional steel bracing to the door. It's simple thin channel. It does add a little weight though, which may require a little bit more tension on the springs.

Try putting a piece of angle iron across the top edge of the door to stiffen it?

Thanks guys. it already has a long a strut across the top though another probably wouldn't hurt. With 16' across, the issue is the door is too flexible, we're talking about 1-2" of deflection on the door when the wind blows. And the sides are tight as they can get against the frame, its just the middle. The old opener effectively push the middle of the door against the frame, the jackshaft one does not.

Forgive the terrible drawing, but I feel like I've seen something like this before, where when something closes, a sort of hook glides into a slot and latches as the door closes, I just can't remember what.

My google searches have pointed to something called "garage door fishing" where people push the top of the door in to get access to the safety cord, similar issue.

look into hardware for hurricane rated doors, I know in FL I've seen ones there the top panel has a piece that slides into a bracket on the wall in the middle top to keep it from getting pushed in
