This beautiful, semicircular balcony umbrella has a stable steel construction, and is perfect for shading somewhat narrower seating areas from the sun. Its design means it can be placed directly on the wall of the house. Sat beneath the open parasol, it's perfect for enjoying hot days outside. The included crank lets you easily open and close the balcony parasol. The air vent ensures air passes through the fabric, preventing heat from accumulating beneath the parasol. The parasol provides reliable UV protection too.
