Abstract: In one aspect, a tensioner assembly for adjusting the tension of a tensioned drive member of a covering includes a first assembly component and a second assembly component, with the first assembly component configured to be non-movably coupled to an associated track rail of the covering and the second assembly component configured to be movable relative to the first assembly component. Additionally, the second assembly component is configured to be coupled to a looped portion of the drive member to allow the tension of the drive member to be adjusted by varying the position of the second assembly component relative to the first assembly component.
