Abstract
Abstract A landing for a ladder or the like includes a support bracket adapted to be secured to the upper end of a ladder by a tie bar passing through a rung thereof. The bracket includes a bar rigidly disposed in the channel cavity of the ladder rail, and a support beam extending laterally from the bar outwardly from the side of the ladder. A plate is disposed horizontally with one edge adapted to rest on a roof or sill surface of the structure on which the ladder is leaning, with a medial portion of the plate resting on the support beam. The plate provides a safe egress from the top of the ladder to the roof or sill.
