Cantilever design lets this 11 x 9-ft patio umbrella project shade away from the pole so you can arrange seating freely underneath. The double-tier vented polyester canopy allows air to flow through to help reduce wind pressure while providing sun protection and light water resistance. Eight heavy-duty metal ribs and a sprayed aluminum pole create a stable triangular support over the cross base. An easy crank lift opens and closes the canopy, while the tilt system and 360 degree rotation help you follow the sun without moving the whole umbrella.
