ABSTRACT:
Large contact areas braces for attachment to the siderails of a ladder maintain the top end of the ladder away from the work surface against which the siderails would ordinarily rest. Each brace provides a large surface area to contact the work surface to prevent defacing of the work surface by the side rails of the ladder. The large contact areas of the braces grip the work surface to prevent the ladder from slipping or sliding. The braces have contact pads that pivot horizontally so that the ladder can straddle corners.
