From the looks in your photo it should go higher. With one hand on the roller take the other hand and release the spring loaded catch and push the roller out. It should go another notch higher. Do one side at a time. If you have trouble extending it the arms may need to be taken off for cleaning and lubrication. Zip-Dee also makes a optional handle that gets put on the arm and may help extending it if you have trouble with it. Fully open the entry door will clear the awning material. I try and be careful with ours and roll it up at the first signs of wind speed picking up and if you expect to leave it extended and it may rain be sure to lower the rear arm to allow rain to run off. Water is heavy and will surely damage things at full extension. Check out the Zip-Dee website they have links to U-tube videos that will show how to open & extend and also how to remove the arms for lubrication.

There are four positions/holes for the upper arm pins of the Zip Dee to be set in ... in hole #4 on each end, it's fully extended....it looks like you may have the awning arms in hole #3...
