Abstract
An intermediate rail, also known as a day/night rail, for placement between the phases of pleated window shade that has at least two distinct phases. The intermediate rail has a fingertip recess running substantially along the entire length of the rail. Additionally, the fingertip recess is sufficiently wide to enable a user's fingers to enter the recess in order to grip the rail so that the rail may be moved.
