Abstract
A level adjusting device for the bottom rail of a window covering is disclosed. This device has a housing having a base, a top and a sidewall extending between the base and the top. The top has an opening through which a lift cord passes. The base has a first opening through which a lift cord passes and a second opening. A spindle is positioned within the housing, such that the bottom end of the spindle is positioned over the second opening in the bottom of the housing. That bottom end is configured to receive a tool for turning the spindle. The spindle has a peripheral edge with spaced apart notches that are engaged by a projection extending from the housing. Turning the spindle causes the lift cord to be wound around or unwound from the spindle which shortens or lengthens that lift cord to level the bottom rail.
