This patio umbrella is water-resistant and blocks up to 98% of UV rays. Outdoor umbrella shades your 42" to 54" round, square, or rectangular table and 4 to 6 chairs. Ideal for residential and commercial spaces, such as gardens, pools, porch, balconies, lawns, and any other outdoor places. An aluminum pole and 8 steel ribs, finished with a rust-free powder coat in black matte, provide better support for the market umbrella. Please check the "pole diameter range" of the base to get a nice match. Crank the handle for easy opening and closing, tilt with a push button to maximize shade by tilting the canopy as the sun's position changes, which will keep you away from the hot sunlight throughout the day. The wind vent at the top of the umbrella allows hot air to circulate and adds stability in case of sudden gusts of wind. All that's left is to enjoy the outdoors.
