headrail

The headrail is the upper horizontal component of a window treatment, serving as the primary support for the blind or shade and housing the operating mechanism. It is mounted to the window frame or surrounding structure with brackets and may be visible or concealed behind a valance. Headrails are typically made from materials such as extruded aluminum, steel, wood, or durable plastic, and are offered in a range of finishes to match decor. The length of the headrail matches the width of the blind or shade and is designed to provide rigidity and support for the fabric, slats, or roller.

In horizontal blinds, the headrail encases the tilt mechanism and the lift cords or ladder system that raise, lower, and tilt the slats. For roller shades, the headrail is the roller tube or a cassette that winds the fabric and may house a clutch or spring mechanism. Pleated and cellular shades often place cord locks or tensioning devices within the headrail. The headrail also serves as the anchor point for mounting brackets and, in many designs, for a decorative valance.

Installation typically involves attaching the headrail to brackets aligned with the window frame, ensuring a level fit and proper operation. Maintenance includes periodic cleaning and inspection of cords, springs, and fasteners for wear or signs of damage. Replacing a headrail is commonly done as a unit with the blind or shade, particularly when the mechanism or fabric is damaged.
