Convert your existing manual-spring driven awnings to a simple manual crank operated Awning. No more springs, no more locking and unlocking travel locks or fishing for pull straps! Just turn the crank mechanism using the telescoping crank handle (included) and once it is fully open, slide the rafter arm up to the roller tube and tighten the rafter knobs. Now you can raise the roller with the lift handles to an desired pitch. It's that simple and easy!
