A longitudinally and pivotally adjustable tray for a worktable which is mounted on the lower end of a traversing bar extending transversely across the table; the traversing bar is at both ends provided with antifriction rolling means and rail means are provided along the lower edge of the worktable to enable the traversing bar which supports the adjustable tray to be longitudinally moved along the table; the worktable may be inclined relative to a horizontal ground surface as is frequently the case in drafting tables and similar worktable arrangements and the tray is pivoted on a bracket extending upwardly from the lower end of the longitudinally movable traversing bar so that the tray may be adjusted in a horizontal position relative to the inclined position of the worktable.
