A pair of ladder brackets held together by an elastic tie at one end of each having U-shaped clamps at the other ends for engaging the narrow sides of the side rails of a ladder when the brackets are fitted to the outer wide sides of the side rails. The elastic tie holds the U-shaped clamps against the inner wide sides of the rails. The brackets can be slid along the rails without interference from the rungs. The free ends of the brackets engage the roof of a building against which the ladder leans, to prevent the ladder from being displaced sideways. The brackets can be carried in a small package up a ladder by a user, and installed while the user is standing on the ladder.

A stabilizing attachment for a ladder having first and second side rails of substantially rectangular cross-section joined at intervals by rungs, wherein first respective sides of said rails face outwardly away from each other, second respective sides of said rails face inwardly toward each other, third respective sides of said rails face to a first side of said ladder, and fourth respective sides of said rails face to a second side of said ladder, said attachment comprising first and second elongated brackets intended, when fitted respectively to said first and second side rails, to engage the roof of a structure against which the ladder leans for preventing displacement of the ladder along the edge of the roof, each of said brackets being substantially the mirror image of the other, each bracket having an elongated portion terminating at one end in a generally U-shaped clamp extending to one side of said elongated portion, said clamp being contoured to fit around the third side of one of said rails and to overlap in part the second side of said one rail when said elongated portion lies against the first side of said one rail with its other end extending away from said second side of said ladder, adjustable means fitted to said elongated portion of each bracket near said other end thereof, for engaging said fourth side of the rail to which said bracket is attached, and resilient means connected between said elongated portions in the region of said other ends extending away from said second side of said ladder and pulling said extending portions toward each other when said brackets are fitted to said side rails for holding said clamps tightly against said respective second sides of said rails, said brackets being slidable along said rails when fitted to said rails for adjusting the position of said attachment along said ladder.
