Abstract
In one aspect, a leveling assembly for adjusting the levelness or skew angle of a bottom rail of a covering for an architectural structure includes at least one movable or slideable component configured to be moved or slid laterally relative to the bottom rail or a headrail of the covering to adjust the length(s) along which one or more of the lift cords extend within the bottom rail or headrail, which, in turn, adjusts the effective length of such lift cord(s) defined between the bottom rail and the headrail of the covering. Such adjustment of the effective length(s) of the lift cord(s) results in the horizontal orientation or skew angle of the bottom rail being varied, thereby allowing the levelness of the bottom rail to be adjusted, as desired.
