ABSTRACT:
A head rail for an adjustable roller shade has two tubes and an extension bar. Each one of the tubes is circular in section and has an adjustment slot and a fabric slot. The adjustment slot is longitudinally formed in a periphery of each one of the tubes. The extension bar is adjustably mounted in the tubes. The tubes are fastened on the extension bar with a short exposed portion of the extension bar to form a desired length of the head rail. Additionally, when the exposed portion of the extension bar is long, the head rail further has at least one connection sheath sleeved around the exposed portion to strengthen the head rail and prevent a shade fabric mounted in the fabric slot from being ruffled or twisted when the head rail is rotated.
