Abstract
A multi-use support apparatus mounts a ladder to a support structure. The support apparatus can be configured for use with different support structures, such as parapet walls, flat roofs, sloping roofs and vertical beams or purlins. The support apparatus has a frame and a platform mounted on and supported by the frame. A pair of spaced ladder support brackets mounted on the frame support the upper end of the ladder therebetween.
