A ladder rack mounted on top of a vehicle includes upstanding guide stops at one end only of the rack on each side frame member for holding one end of a ladder while the other end is being pivoted onto the rack. An upstanding stop on an end cross-frame member engages a rung of the ladder adjacent one end and a coil spring mounted on a cross-frame member at the other end of the rack includes a perpendicular finger end portion adapted to be pivoted from a horizontal position to a vertical position in engagement with an adjacent rung of the ladder to apply pressure downward and towards the stop on the other cross-frame member.
