A top bracket fixture (A) comprised of a left and right side that is attached to the top of a sectional garage door (B) on both the left and right end styles (C). They allow the top section to independently tip inwards before there is any upward movement of the door. This invention is comprised of a rectangular steel plate (1) with a ninety degree bend at the top (6). With a series of specified punched holes (2), and two small pieces of steel tubing welded to the outside of said steel plate (4), but not extending past its width. A secondary steel plate (6) smaller in width and height is welded to specified steel tube (3) at the bottom of the steel plate (6) and no wider than its width, while a second steel tube (5) of the same dimensions is welded to the top of the secondary plate (6), so as to extend past the width of said plate, creating a left and right bracket. Both steel tubes (5/3) are welded to the same side of said steel plate (6). The smaller rectangular steel plate (6) is then aligned between the two pieces of tubing (4) that is welded to the larger steel plate (1), a steel pin (7) is inserted and welded to the steel tube (4) of first said steel plate (1) thus creating a hinge between the two steel plates. A standard two or three inch roller (8) is inserted into the tubing extending outwardly from the smaller steel plate (5). This is inserted into a standard horizontal 12" or 15" radius curve track (9).
