At 18" wide, this classic schoolhouse shade is the widest we offer, with the most overall massive feel. It's got the girth needed for commercial applications. Most old homes lack rooms big enough for it, but if you've knocked down walls to open things up, it's possible. (Just think it over first and repeat the phrase "very large shade" while doing so.)The 001OP-18 can fit a variety of fixtures, from the stately Jackson Park to the humble Thurman. Also, this schoolhouse shade fits all our 6" fitter Compact Fluorescent fixtures. See more shades with a 6" fitter.
