Abstract: A load leveling device for a ladder in the form of a compensator boot which slips onto a lower end of one of the legs of the ladder. The boot includes a vertically elongated block of homogeneous, molded plastic or rubber material and a vertically extending socket in the block opening in the upper end face of the block. The socket has cross-sectional dimensions sized to allow the lower end of the leg of the ladder to slide into the socket and has a blind lower end spaced vertically from the lower end face of the block by a distance compensating for the angle of the associated roof surface.
