Powder-coated metal frame and eight heavy-duty metal ribs support a polyester canopy to create steady shade over outdoor seating or dining. The 160 G polyester fabric is wear-resistant and helps block strong sun while remaining light enough for easy handling. A vent at the top of the canopy promotes air circulation so wind can pass through more smoothly. The crank handle on the pole lets you open and close the umbrella quickly without lifting the canopy by hand. A spring button connection between the two pole sections makes assembly straightforward and allows simple takedown for storage when not in use.
