We make our octagonal MARKET UMBRELLAS in solid teak, not in a weaker wood that may warp or rot. The 9' umbrella with 1 1⁄2" pole fits our 30", 36", 42", 48" and 50" round dining tables, 36" bar tables, and 36" and 42" round coffee tables. The 10' umbrella with 2" pole fits our 60", 66", 72", 92" and 98" dining tables. And, the 11.5' umbrella with 2 1⁄2" pole fits our 100", 114", and 122" tables. We recommend the solid metal base with each umbrella which fits neatly underneath your table. Our combination of teakwood and Sunbrella ® outdoor fabric creates a market umbrella of superior quality. For your convenience, we have added a pulley system to our market umbrellas. This addition will facilitate the raising and lowering of the canopy.
