Abstract
A ladder tray (10) is provided with a generally rectangular tray (11 ) having a panel (12) surrounded by a flange (28) which projects both above and below the panel. Two pairs of slides (31) can slide along the flange (28) at respective ends (15, 16) and the slides (31) carry the upper ends of legs (32) of U-shaped tray supports (26). The slides also include lockable pivot screws (33) which can lock both the legs (32) and the slides (31) against movement and allow bridge portions (25) of the tray supports (26) to bear against a portion of a ladder to which the tray assembly (10) is attached.
