Abstract: The ladder stabilizer apparatus provides for removable attachment to two rungs of a ladder. The case provides pivoting sleeves that may be indirectly or directly controlled by the apparatus crank, whereby either the sleeves or the sleeves with arms with optional vertical rollers are moved toward and away from the ladder. Rollers are provided for a given surface contact with the apparatus. Movement of the sleeves and the sleeves with arms provides for the contact devices to be positioned partially around a structure or object corner, within a corner, or any position between. The contact devices may be positioned outside boundaries of a window, for example, to provide a user best access to a window or other area that is not designed to have a ladder rested against it. The apparatus may be adjusted while in use.
