Abstract
A ladder leveler includes a frame unit that is adjustable in two degrees of freedom and has a wide range of adjustment. The rungs of a ladder being leveled are supported, and brakes are located between the rung supporting element and the remainder of the frame unit. The brakes can be located between the rung supporting element and crossbars on the frame unit and/or between the crossbars and stanchions of that frame unit. At least two rungs of the ladder are supported. If three rungs are supported, one of the rungs will be supported from beneath that rung, and the stanchions are telescoping.
