LADDERS WITH INTEGRATED SUPPORT, LADDER COMPONENTS AND RELATED METHODS
A ladder is provided having a first assembly and a second assembly slidably coupled with the first assembly. The first assembly includes a first pair of spaced apart rails and a first plurality of rungs extending between and coupled to the first pair of spaced apart rails. the second assembly includes a second pair of spaced apart rails and a second plurality of rungs extending between and coupled to the second pair of spaced apart rails. A support apparatus is coupled with the first assembly and includes one or more arms that are pivotally displaced from a refracted position to a deployed position responsive to displacement of the first assembly a specified distance relative to the second assembly.
