ABSTRACT:
A ladder step platform can be mounted on any ladder having hollow rungs extending between ladder rails. This ladder step platform is especially intended for use with conventional extension ladders. The ladder step platform includes a tread or step plate extending between opposite side plates. The spacing between side plates can be adjusted so the ladder step platform will fit ladders of different width. A support rod insertable though hollow ladder rungs pivotally supports the ladder step platform with the side plates positioned on the outside of the ladder rails. A lower adjustable rod abuts the ladder rails to hold the tread or step plate in a horizontal orientation extending beyond the sloping ladder for easy access.
