Abstract
Ladders and ladder components are described herein, including multipurpose and adjustable ladders. In one embodiment, a ladder includes a first assembly having rails and rungs, a second assembly having rails and rungs, and one or more hinges coupling the first and second assemblies together such that the first and second assembly may be positioned relative to one another in at least a position or state and at least a second position or state. A top cap is coupled to the rails of the first assembly, such that when the first and second assemblies are in the first position, the rails of the second assembly do not contact the top cap. When the first and second assemblies are in the second position, each rail of the second assembly is at least partially nested in one of a pair of channels formed in the top cap.
