How do I brace my garage door so the garage door opener doesn't warp the door where attached to the opener?
I have a one car garage door I'm installing a garage door opener to. The problem is the manufacturer of the door doesn't guarantee the vertical aluminum center bar on the top panel of the door won't bend or break during the operation of the garage door opener. How can I brace the L-shaped aluminum bar to take the stress of the door being automatically lifted without warping the bar or the top panel of the door? There is no information listed on the garage door manufacturer's website.
