This 11ft 8-rib replacement canopy is precision-cut for offset cantilever frames with a hanging component — the style where the canopy hangs from the very center top like a pendulum. Rib length is 64 inches, with a fit that feels like original equipment.
Why olefin
Olefin is our upgrade fabric. It is lightweight, fade-resistant, and holds up against stains, sunlight, and wear far better than standard polyester.
- Color locked into the fiber. Solution-dyed means pigment is added during production rather than printed on the surface, so the color cannot wash or wear off.
- Naturally water-shedding. Olefin repels water and resists mildew as a property of the fiber itself.
- Built for full sun. Olefin outperforms standard polyester in UV resistance and colorfastness, making it the right choice for umbrellas in continuous, direct exposure.
- Sustainable through longevity. A canopy that lasts several seasons is a canopy you are not replacing every year.
Features
1. Premium solution-dyed olefin
Crafted from solution-dyed olefin, a polypropylene-based fabric where color is locked into the fiber during production rather than applied on top. The result is a canopy that resists fading, repels water naturally, and sheds mildew — without relying on surface treatments that wear off over time.
2. 98% UV blockage, UPF 50+ rated
Blocks 98% of harmful UV radiation with a UPF 50+ rating, providing meaningful sun protection for everyone underneath — not just shade.
3. Precision fit for hanging style cantilever frames only
Cut specifically for 11ft 8-rib offset cantilever umbrellas with a hanging style canopy, rib length 64". Does not fit supported bar cantilever, square, double-tier, or market patio umbrellas.
4. Stays taut in every condition
Extra-deep reinforced rib pockets grip all 8 ribs firmly, maintaining canopy tension and a clean overhead profile through wind and weather the way original equipment should.
5. Composed when it’s at rest
Tie rope keeps the canopy gathered and neat when the umbrella is closed, maintaining the polished look of your space even when shade isn’t needed.

Fitting your new canopy
No tools are needed for this style — it fastens with Velcro and ropes. Our step-by-step hanging style installation guide walks through it in 5 steps, and includes a customer video filmed on an 11ft umbrella exactly like this one.
Prefer the standard fabric? The same canopy is available in 600-denier polyester in other colors. Not sure which frame style you have? If a horizontal bar runs from the pole out to the canopy, you need a supported bar canopy instead.
