Abstract
Ladder support apparatus and methods are disclosed. In one embodiment, a support assembly adapted for use with a ladder includes at least one elongated member adapted to extend between first and second legs of the ladder when the ladder is positioned in an operating position. First and second coupling assemblies are coupled to the elongated member at spaced-apart positions on the elongated member. The first and second coupling assemblies are adapted to be clampably coupled to the first and second legs of the ladder, respectively. The support assembly advantageously permits the ladder to be operated over non-uniform surfaces without permanent modification of the ladder.
