Abstract
An improved safety attachment for a ladder in which the attachment is collapsible to render it more compact for storing and handling purposes yet the attachment can be readily expanded for use on a ladder. The attachment includes a pair of spaced sides which are coupled together by a pair of vertically spaced cross-pieces with the cross-pieces being either removable from connection with the sides or articulated with respect to the sides so that the sides can be moved toward and away from each other to form a compact unit to facilitate storage and handling of the attachment.
