A user-sizeable headrail assembly that may be easily and readily cut-down to size by the consumer; includes a pre-assembled, cordless headrail and a cutting jig. The preferred headrail has an elongated track, a pinion rod, and multiple carriers which slide along the track and rod. The cutting jig is sized for removable location between a pair of carriers at a desired location along the pre-assembled headrail for simultaneously cutting the elongated track and pinion rod to divide the pre-assembled headrail into a first scrap portion and a second useful portion having a desired length that is less than the initial length. For this purpose, the cutting jig includes an upper track support portion including upper contact members that contact the opposed sides of the elongated track and a lower rod support portion including lower contact members that extends downwardly from the upper track support portion and surround the pinion rod in the interior of the elongated track.
