Ladder bracket on top rung of ladder. These are made in various styles. Some fasten to rungs. This one attaches to the siderails. It is not, therefore, likely to depend upon a defective rung and so it is safer. They are used as shown on the outside of the ladder to hold a plank at the top of two extension ladders in painting roof cornices. It is possible to swing these brackets to a position on the under side of the ladders. There they make an excellent scaffold from which to work on a wall or window frame.
