Four-sided shade coverage combines an 11 x 9 in cantilever canopy with 360 degree rotation and an easy tilt system so you can follow the sun without moving your furniture. The double-tier vented polyester canopy helps air pass through to reduce wind pressure while resisting sun and light water. Eight heavy-duty metal ribs and a stable triangle structure with a sprayed aluminum pole support the 45 lbs frame. A crank lift opens and closes the umbrella quickly, while a fixing strap secures the canopy when folded. For added stability, use a 196 lbs base, sold separately.
