A sectional door (2) is disclosed that includes a safety system. The safety system includes a shield apparatus (12), an improved support track (6), reverse angle track shields (80), and hemmed roller track edges (38) to prevent injury or harm to body parts errantly placed within or around the support track (6) during the opening or closing of the sectional door (2). The sectional door (2) includes a plurality of door sections (8) hingedly joined in an edge-to-edge relationship to form the completed sectional door (2). The sectional door (2) further includes support rollers (10) attached to the door sections (8), and a pair of support tracks (6), in which the support rollers (10) are confined. Each support roller (10) further includes a circular or rectangular roller shield (12) that is mounted to the axle (26) of the support roller (10) outside of the support track (6) where it is proximate the support track (6) in such a manner as to limit or prevent any fingers from engaging within the support track (6) with the support roller (10). The dimensions of the protective shield (12) are larger than the support rollers (10) so as to provide transport guidance within the support track (6) where track sections meet. The reverse angle track shields (80) are constructed of a solid metal piece so as to prevent objects from passing between the support track (6) and a mounting surface, with the outside edge being folded into a single hem (138) or covered with a protective material (140). The adjacent edge of the support track (6) is formed into a folded hem (38), either outwardly or inwardly, to prevent fingers from being cut.
