An accessory positionable on top of a ladder has a pair of brackets which may be secured about the upper ends of the ladder rails and has a laterally extending beam secured to the brackets for resting on the upper rung of the ladder. The brackets each include a leg to which laterally spaced sidewalls of a work tray are pivoted so that the tray may be rotated from an inoperative position overlaying the front of the ladder to an operative position extending transversely from the front of the ladder to the rear of the ladder, the brackets having seat portions on which the sidewalls may rest in the operative position. The rear of the work tray supports a pair of laterally slidable stabilizer arms which include a respective transversely extending limb for engaging against a wall ascended by the ladder. The spacing between the front of the ladder and the wall is thus extended by the limbs and the work tray so that one on the ladder with the accessory in the operative position may stand on a higher rung than without the accessory. A support handle may be extended out of the work tray into an operative position for additional support for one standing on the ladder, the handle being foldable into the tray when inoperative.
