ABSTRACT:
A pair of brackets for the top end of a ladder, which can be slipped over the ladder rails and pinned in attached relation thereto, are of light weight, low cost pressed steel construction, and are formed to accept as a spacer member a piece of two-by-four timber, to permit supporting the ladder against the face of a building such as a damage-susceptible siding, or in positioned relation in a window opening, wherein the two-by-four timber spans the window opening and supports the ladder in that opening. An alternative use of the brackets, in one embodiment in combination with a small plywood platform attached to the brackets, serves as a ladder hold-off, for use when working under or adjacent the eaves of a house, and to serve as a supporting platform for a can of paint, or other adjuncts such as tools. The form of the brackets facilitates readily manufacture from sheet steel, with high percentage material utilization, and low scrap generation.
