Six or eight firm steel ribs support the 10-ft polyester canopy, spreading tension evenly so the fabric stays stable in breezy patio, garden, or poolside settings. A steel pole with a hand-crank lift lets you open and close the canopy smoothly without forcing it up by hand, which helps protect the frame over time. The tilt adjustment at the pole joint allows you to angle the canopy as the sun shifts to help maintain shade on seating or tables. The two-piece design installs easily into a compatible umbrella base for outdoor use in commercial or residential spaces.
