Abstract
Door leveling apparatuses are disclosed herein. A door leveling apparatus configured in accordance with one embodiment includes a bracket mounted to a door, such as a vertically-opening sectional door. The apparatus further includes a cable assembly having a first end portion coupled to the bracket and a second end portion coupled to a door lifting system, such as a counterbalance assembly. The first end portion includes an adjuster that enables an operator to adjust the operational length of the cable assembly extending between the lifting system and the bracket, thereby enabling the operator to individually adjust the lengths of two such cable assemblies on opposite sides of the door to align the door with a corresponding opening.
