ABSTRACT:
There is provided a ladder having a leveler attached thereto. The leveler includes a T-shaped gripping device having a sharp edge which contacts the smooth surface of an adjacent slidable rail for locking the rail into position. The slidable rail acts as one of the legs of the ladder to level the ladder. The leveler has an infinite number of increments of adjustment so that the ladder may be used on most any slope.
