To be safe, it is a two man job.

You'll need a ladder about the height of the outside edge of you awning when it is open. Have somone steady that while you unhook the arm from the coach.

Carefylly unwind the arm at the end of the awning and count the number of revolutions you make. My 19' awning formula is 19 turns plus 7. Zip Dee gave me that formula and it may take a turn or so to get the awning to fold the way you want.

After you replace the lock and end, wind the arm the length in footage plus 7.

I just replaced my stabilizer arm that goes to the roof and I had to install 2 pop rivets.

Should be a piece of cake for you and if you have further questions, call Zip Dee. They are very helpful.
