Each of the tracks has an attaching flange 1 which is adapted to be attached to some supporting means upon the ear such as 35 the flange 7 of a Zbar. The edges of such flange may also be peened over, as indicated at 3, to provide callring edges. Each attaching flange has a horizontal ledge or flange l which Q slightly inclines downwardly in an outward direction. The rollers 5 of a sliding door 6 are adapted to travel upon the flange 4 which forms the track proper. The inclined feature 15 of the track flange l has a two-fold purpose. In the first place, it more readily sheds the rain and snow, and in the second place, it causes the rollers 5 to gravitate towards the outer edge of the track flange with the result 50 that the door will travel clear of the side of K00 Jll
