ABSTRACT:
A ladder stabilizer is disclosed which is an add-on to an existing step-ladder which requires no alteration or modifications of the step-ladder. The apparatus consists of a V-shaped member supporting L-shaped telescopic legs, the V-shaped member being attached to two parallel cross members which join the front and back legs of the ladder together and when the ladder is rocked in a lateral motion the L-shaped legs fall inward until they are in stable contact with the ground surface, thus being self-adjusting.
