Abstract: First and second members are attached together by an attachment device which includes a key hole shaped slot provided in the first member and having an enlarged entry portion communicating with a narrow slot portion. An aperture is provided in the second member and a bolt having a threaded shank and an enlarged head is press fit part way into the aperture of the second member so that the enlarged head is spaced somewhat longitudinally away from engaging the second member. The second member is hung on the first member by inserting the enlarged head of the bolt through the entry portion of the key hole shaped slot and then sliding the second member laterally of the first member so that the shank enters the narrower slot portion.
