Flannery offers prefabricated Inside and Outside Corners for intricate ceiling designs that utilize our Strata Acoustical Ceiling Cloud Edge trim. Prefabricated corners are factory mitered and then welded together to prevent separation during the edge trim installation. These welded corners also allow the installer to maintain a straight and true layout of any rectangle or square ceiling. Factory welded corners come with 8” legs in each direction, however, custom leg lengths can be ordered. Factory cutting and mitering for custom ceiling projects are also available.
