PUBLIC SAFETY ANNOUNCEMENT!
It isn't rocket science to remove your roller tube from a Zip-Dee patio awning and remove/replace the fabric, BUT IT SURE HELPS IF YOU HAVE DONE IT BEFORE! Being a veteran of many installs and re-coverings in the awning arena, I can say that with certainty.
Safety is of prime importance when de-tensioning the roller spring. I have seen too many folks with bruised/broken limbs and fingers.....all while trying to save a few dollars.
SUCK IT UP AND PAY THE EXPERTS!!!!! What is your health and safety worth. Want to get bloody and/or bruised.......be my guest! If you DO have an awning 'expert' locally, why not watch them do an installation or repair. You can easily judge just how good they really are and make the decision for yourself.
BE SAFE OUT THERE!
