ABSTRACT:
A sway brace is attached to each of the opposite sides of a step ladder. The attachment is made by a bolt passing through aligned holes in the brace leg and an associated ladder leg. The bolt hole in the brace leg is oversized to permit it to swing to a bracing position. A compression spring takes up the resulting looseness.
