In American English, pullout is one word when it functions as a noun or an adjective. It is two words, pull out, when it functions as a verb. British writers usually use the hyphenated pull-out where Americans use pullout. Canadian and Australian English are inconsistent on the matter; some Canadian and Australian publications use pullout, and some use pull-out.
