"3ares"....Here is what you're looking for
ShadePro.
Ours has a piece that slides into the slot on our awning arm and stays there permanently. The main part zippers to the piece in the awning and then can be staked/bungee corded down.
Here's how it works. First you measure the length of your awning and purchase a shade a similar length or shorter. The awning comes in two pieces. One is the "drop" and the other is the "shade". The "drop" is what slides into your awning arm. It can drop down from your awning rail, typically, 6" to 24", your choice. You make your decision by how tall your awning is when open. If you're awning is 8' off of the ground, when open, you would probably want the 24" drop. That way, you can reach the "drop" to zipper the shade on. Again, the "drop" stays in the slot, even when you roll up your awning.
So, if the awning is 8' tall, the "drop" is 2' long, then you would want a 4'-6' shade. When you buy the shade, you have to make the decisions on the lengths and color you want.
