When I replaced my main awning fabric, it was ordered with the 1st strip of aluminum already on the fabric.
I removed the old by extending it about 2', unwinding the spring with only the top part of the support arm still attached to the roller.
Then slid it out with only the 1st stip still attached.
When installing the new awning, I placed a few step ladders to support it as it was slid into place.
Then rolled it up by hand, attached arms, and began to preload (twist) the spring side the required amount of turns. It should have a recomended amount, I think I added 3 to this number.
Not so tough if you give yourself some leverage on the spring side arm.
On the totally new ones I added, I was sure to place brackets in line with the row of rivets that attach the original ribs under the skin.
Your opinion is valued, please not your opinion of someones else's opinion.
