Abstract: Brackets (30, 40) are mounted to respective sides of a hinged step ladder by spaced apart divergent channel forming means (31, 32) on each bracket fitting onto respective swing apart limbs (14, 16) of the erect ladder. The brackets (30, 40) each include a support portion (36), extending beyond one of the channel forming means (32), both to the same side of the ladder, onto which a tray or the like (50) is secured by fastening means (41) so as to provide a stable platform for tool and materials at a convenient height for a user of the ladder. One of the channel forming means (32) may be pivotally adjustable.In an alternative embodiment (FIGS. 13 to 15) one of the channel forming means of each bracket is adjustable in position relative to the other so that the channels may be selectively disposed substantially parallel to each other to fit to a single limb of a ladder or divergent from each other for engagement around opened limbs of a hinged ladder.
