Abstract: A Foot actuated ladder brace for stabilizing ladders with side rails operates by increasing the ladder base width. A channel shaped foot link is pivotally connected to the bottom of one of the ladder side rails as to fold up along the side rail and to swing downwardly to extend along and increase the ladder base. A smaller channel shaped intermediate link adapted to nest within the foot link has a foot end pivotally connected to the outer end of the foot link. The intermediate link has an inward end which is pivotally connected to the outer end of the smallest channel shaped ladder link which is adapted to nest within the intermediate link. The ladder link has a ladder end pivotally connected to the side rail above the bottom of the rail.
