Measure the width of the awning fabric, roll the awning all the way out and measure from the bottom of the roller tube to the ground.

We are talking about the Height of the Vista Shade. If you ordered an 8′ tall screen (drop), it would have a 2′ insert that stays in the awning. This simply slides into the roller tube and stays there. When you want to use the entire screen, zip the 6′ (body) to it and its now 8′ tall. We do this because most people can reach 6′ without a ladder. If you need more help please call customer service 800-328-5100

The Vista Shade is made to work with most awning manufacturers. Check the roller tube and look for an available slot. If you have one open at the bottom, the Vista Shade can slide into that slot. If you are using that slot for something else like a light bar, you will not be able to use the Vista Shade and the LED bar at the same time. 

1) Yes the polycord is sewn in and it will slide right into the roller tube. It goes in the accessory slot.

2) 5′ will hang down when you roll the awning out. The body that you attach by zipper is 6″ giving you a total of 11′ drop.

3) There are 5 grommets

For these awnings, you would need to order the 17′ and 10′ wide Vista Shade. This should give you shades that are the exact same width as your fabrics.
