<p>A longitudinally deformable sleeve for centering a roof panel mounting tab on a roof panel attachment clip unit prior to installation of the clip unit and the roof panels on a building. The centering sleeve has an elongated body with two sides, one edge of each side being connected together by hinge structure, and the opposite edge of each side having a mounting facilitating flange extending therealong. In order to increase the deformability of the sleeve, cutouts are provided in at least one edge of each side, and preferably in both edges of each side. These cutouts may be of various shapes including semi-elliptical, V-shaped, rectangular shaped, or square shaped. A modification of the mounting facilitating flange includes a thickened portion extending along the non-hinged edge of each sleeve side to facilitate the mounting of the sleeve on a support piece of the roof panel attachment clip unit. A further embodiment employs an area of reduced thickness in the mid-portion of each sleeve side together with tapered sleeve ends for increasing the deformability of the sleeve and for decreasing the force needed to deform the sleeve.</p> |
