Step ladders, components for step ladders and related methods
A step ladder includes a first assembly having a first pair of spaced apart rails, a second assembly having at least one rail, and a top cap coupled with the first assembly and the second assembly. At least one of the first and second assemblies may be pivotally coupled with the top cap. The first assembly includes a plurality of rungs coupled with the rails and may exhibit a vertical spacing of a first distance between adjacent rungs, a vertical spacing equal to the first distance between the lowermost rung and a supporting surface (e.g., the ground), and a vertical spacing between the uppermost rung and the top cap that is greater than the first distance. In one particular embodiment, the vertical spacing between the uppermost rung and the top cap is twice the distance of the first distance.
