Abstract: A ladder with bracing is provided. In one embodiment, the ladder may include a first rail assembly comprising a pair of inner rails and a pair of outer rails, the pair of inner rails being slidably disposed in a upper portion of pair of outer rails, wherein a rear surface of each of the pair of outer rails lies in a common plane. A first plurality of rungs may be coupled between the pair of inner rails, and a second plurality of rungs coupled between the pair of outer rails. A brace may extend between and be coupled to the pair of outer rails, wherein the brace includes a first ramped surface, the first ramped surface having a first portion spaced away from the common plane, a second portion immediately adjacent the common plane, and a transition portion extending between the first portion and the second portion.

Abstract: Ladders and ladder components are provided including a rung assembly that provides an alert to a user of the ladder that they are standing on a particular rung or step. In one example, the lower most rung or step of a ladder includes a rung assembly having an alert mechanism. The alert mechanism may provide an audible and/or other sensory alert to a user when they step on the rung assembly so that the user recognizes their position relative to the ground or supporting surface. In one embodiment, the rung assembly is configured such that a front edge remains in a constant or fixed position relative to the rails to which it is coupled so that a user can rely on a fixed or constant position of the front edge of the assembly when climbing or descending the ladder.
