Abstract
An apparatus is provided for fitting at an upper portion of a ladder. It is adapted for use in situations where an electrical service crew member must work on electrical equipment (such as transformer boxes) which are mounted on upper portions of building walls. The apparatus provides a safe and stable support for the ladder. The apparatus provides this support while keeping the ladder located an adequate distance from the wall. The crew member can thus comfortably stand on the ladder and still have access to the equipment to remove the cover of the box and work on its contents.
