Abstract
A ladder standoff includes at least one bent plate that is configured to be detachably engaged with at least one ladder rung of a ladder by at least one connection plate that is configured to be detachably connected to the bent plate and to the ladder rung. The ladder standoff may be attached to a ladder and used to secure a ladder to a vertically-extending building wall structure at a selected distance. The length of the ladder standoff can be extended in a substantially horizontal direction in relation to the vertically extending ladder and vertically extending building wall to provide a ladder standoff with variable lengths to accommodate different distances between the ladder and the surface of the vertically extending building wall.
