Abstract
Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position. In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.
