摘要： A ladder having a foot having a plastic body with a recess which receives the end of a first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has a front edge. The foot has a metal rail fastener which extends through the body and the rail to attach the body and the rail together. The foot has a pad having a rigid plate with a rubber outer layer surrounding the rigid plate and a pad fastener hole that extends entirely through the rigid plate and rubber outer layer, the outer layer of the pad having a bottom with treads. The foot has a metal pad fastener that extends entirely through the pad and entirely through the base to attach the pad to the base so the rigid plate is between the treads and the base of the shell. A ladder foot. A method.

摘要： A ladder having a first rail and a second rail. The ladder having a standard rung having a width permanently attached to the first rail and the second rail. The ladder having a first wide rung having a width greater than the width of the standard rung, which is permanently attached to the first rail and the second rail. The ladder having a second wide rung having a width greater than the width of the standard rung, which is permanently attached to the first rail and the second rail. The first wide rung and the second wide rung are disposed in a work zone of the ladder. The work zone of the ladder is where a user typically stands on the ladder while performing tasks. The standard rung is disposed outside the work zone.
