However, please note that in bad weather such as wind and heavy rain, please roll up the retractable awning, which can extend its service life. The awning is designed for drill-free installation and comes with floor-to-ceiling poles. This avoids damage to the walls and makes this patio awning suitable for all types of ceilings.

The patio canopy angle is adjustable from 0 – 90° by turning the crank, and the tarp length is easily adjustable from 0-71 inches.
