Abstract
Parallel tubular arms removably slide into the openings through the openings in the side rails and the hollow rungs of aluminum ladders. A swivel on at least one arm protruding through both ladder rails turns to secure the handrail to the ladder. Orthogonal extensions of the arms support the handrail in a fixed position away from the ladder. Depending on the relative lengths of the supports the handrail may be in parallel or sloping alignment with the ladder. Handrails may be installed on both sides of the ladder and a restraining means secured between the handrails.
