The Trinidad II 9-ft Octagon Market Umbrella is packed with quality features. The unique crank and open system with built-in-auto-tilt allows you to angle the umbrella against the elements and relax in the shade. The sturdy 1.5-in diameter powder-coated, rust- steel pole and 8-rib canopy support system add the final touches to this quality umbrella. The canopy is covered in weather, and polyester fabric, plus features a single wind vent that allows air to easily escape while limiting wind damage.
