This 7.5 foot octagonal market umbrella includes 1/2″ fiberglass ribs, a 1.5″ diameter coated aluminum pole, and 9 oz. marine grade canopy and an easy to use manual pulley lift system. Our commercial grade fiberglass market umbrellas are made of hotel and resort commercial use. Fiberglass market umbrellas are excellent for wind resistance as the fiberglass bends with the umbrella.
