Keep your decks, outdoor dining areas, or pool-side patios shaded with this California Umbrella ALTO 118 OLEFIN Venture 11' round pulley lift umbrella with 1 1/2" bronze aluminum pole. An essential addition to commercial environments, the Venture series offers umbrellas that are created with superior materials and exude a classic, sophisticated appearance. This umbrella features a 1 1/2" thick, double wall bronze aluminum pole with sleek, stainless steel hardware for a robust foundation. Its 1/2" thick, high-density fiberglass ribs bend with the wind without snapping or breaking, yet provide excellent support for the canopy. In addition, the double wind vent allows for sufficient air flow to ensure stability and prevent the umbrella from moving with strong wind gusts. The Olefin fabric is water-resistant but not water-proof and is not intended for use in wet conditions. During inclement weather, please store umbrellas in a dry location or cover with a protective umbrella cover sold separately. This umbrella's 11' size has sufficient area coverage, providing multiple guests with relief from the sun's rays. Its pulley lift also allows staff members to easily open or close the umbrella as needed. The pulley's simple, braided rope bears the weight of the canopy while opening and closing to eliminate force and fatigue, while the convenient pin stop in the center mast keeps the canopy in place while open. The canopy's fabric is made with durable, synthetic Olefin fibers that offer better fade resistance than polyester and cotton counterparts without the added expense that comes with acrylic canvases. It's an excellent choice for budget-conscious consumers, and is sure to provide a professional look for years to come.
