Abstract
A ladder stand-off includes an extension beam and first and second stand-off sections slidingly mounted on the extension beam, so as to provide an adjustable span. Each stand-off section includes a support beam and an arm fixedly connected to the first support beam. A contact element is pivotally contacted to the outer end of each arm, allowing the device to be used with flat, curved and corner surfaces. The two arms preferably extend in an outward direction so as to be angularly divergent with respect to each other. The device can also be implemented as a ladder stand-off kit having multiple extension beams of different lengths that can be used interchangeably with the two ladder stand-off sections. In this case, the desired extension beam would be assembled with the first and second stand-off sections to form a ladder stand-off.
