Abstract
A ladder leveler is disclosed in which two pivoting arms are mounted on a base plate to provide a self-adjusting and infinitely adjustable device. The two arms cooperate with a movable locking member or tumbler which is mounted between the arms and shaped to permit the arms to self adjust for uneven ground and lock the arms against movement when weight is placed on the ladder. The device may be readily secured to and removed from the base of a ladder without extensive disassembly.
