ABSTRACT:
A support platform for a ladder is disclosed which is arranged to be assembled with eight bolts by placing a platform on to a pair of straps which have hook members at either end thereof. Further, a spreader bar, that serves as a handle, is fastened across the upper portions of the straps so that the upper portion is stiffened. A leg is spaced inwardly from the hooks at either end of the straps to provide guidance of the platform onto the rungs of the ladder; leg portions are elongated for the purpose of proper engagement with the rungs of the ladder.
