Abstract: A window treatment system may include one or more lift rings (e.g., cord guides) for guiding flexible members (e.g., cords and/or ribbons) when wrapping around a roller tube of the window treatment system. Each of the lift rings may comprise a body that is ring-shaped and defines a central opening configured to receive the roller tube. The body may extend from a first end to a second end, where the first end is spaced apart from the second end by a gap. The body may be configured to be deformed by the first and second ends of the body being pulled in opposite directions to increase the size of the gap, such that the roller tube may be received through the gap. The body may be configured to reform when released, such that the roller tube is received in the central opening of the body.
