The first arms are usually spring loaded and the ones after those furl to retract the awning or unfurl to extend it.

The tension from the springs or pressure of the gas ensures they open and close softly. Another turn or push and the awning extends providing blessed relief from the sweltering sun. These may extend and retract either manually or automatically depending on the type of awning. A manual retractable patio awning uses articulated arms that open and close in stages.

Articulated and telescopic arms. The arms work because of a spring tension system or gas pistons. The spring loaded arms and angled design coupled with the front bar weight helps draw the retractable canopy out. Aluminum types roll up into the cassette pushed by arms on the sides of the window.

Many people assume they push the cover open but the arms simply automatically follow the cover as it opens or closes. Retractable awnings mean that you can move it in and out.

The awning rolls up into the cassette that protects it from the weather when not in use. Manual awning a detachable hand turned crank is used to rotate the roller tube.
