Abstract (en)
An improved safety attachment (10) for a ladder (11) 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 (14) which are coupled together by a pair of vertically spaced cross-pieces (36) with the cross-pieces being either or articulated with respect to the sides so that the sides can be moved toward and away from each other or the cross-pieces can be coupled to the sides when the sides are collapsible, so as to form a compact unit to facilitate storage and handling of the attachment. <IMAGE>
