A ladder system comprising a ladder having side rails and a plurality of steps disposed between the side rails. The ladder system also is comprised of at least one corner brace for supporting a bottom step of the ladder. The corner brace is attached to a side rail of the ladder and the bottom step. Additionally, the ladder system is comprised of at least one caster assembly integrally attached to the corner brace for allowing the ladder to roll. Preferably, the caster assembly and corner brace are disposed on the ladder such that a predetermined weight placed on the ladder prevents the ladder from rolling. The corner brace is preferably comprised of a first portion, a second portion connected to the first portion and a third portion connected to the second portion.
