Abstract: This bracket and track assembly can be used for sliding door assemblies and facilitates the alignment and installation of such doors. The track includes a pair of spaced, inwardly facing channel-shaped track members, supported by a plurality of longitudinally spaced, U-shaped bracket members embracingly disposed about said track members. The upper portion of each bracket member includes a rotatably mounted locking clip and a pair of arcuate slots receiving opposed legs of the clip. The arcuate slots overlap the upper, inner edges of each track member so that the clip legs exert an outward force against the track members when the clip is rotated, tending to urge said track members into engagement with said bracket members.
