ABSTRACT:
Disclosed is a new stepladder stabilizer for improving stability of a conventional folding stepladder during use on soft areas into which the stepladder might tend to sink and additionally for improving the lateral stability of the stepladder. The stepladder stabilizer comprises an elongated rigid pad engagable with the stepladder supporting surface, normally the ground or a floor. The pad comprises left and right sections telescoped together to form a rectangular pad with an planar engagement surface on the bottom thereof. An integrally formed socket projects upwardly from each pad section wherein the stepladder leg tips may be removably inserted to hold the pad in alignment directly thereunder. Weight applied to the leg tips is spread over the area of the pad engagement surface whereby increasing the effective surface area of the leg tips. Spacing between the sockets may be adjusted to match the spacing of the legs by sliding the left pad section longitudinally relative the right pad section.
