ABSTRACT:
In combination with an extension ladder, an L-shaped bracket is provided. The bracket has at least one first leg longer than the distance between successive rungs of the ladder. The first leg is placed on one side of an upper rung and on the other side of a next lower rung. A short leg integral with the first leg projecting generally at right angles to the first leg, is placed on top of the upper rung and extends beyond the rung. It is adapted to support an accessory, such as a paint can or a tray. A clamp on the projecting leg insures against dislodgement of the holder. In the preferred embodiment, two L-shaped brackets are connected to an accessory carrying bar that projects beyond the sides of the rails of the ladder, and the clamp includes a plate wedging between the bar and a rail of the ladder.
