ABSTRACT:
A ladder attachment for securement to a ladder leg which can function as a ladder standoff, ladder leg extension or roof ridge hook. The ladder standoff arrangement permits the ladder to be supported a predetermined distance from a wall, enables the ladder to be used as a scaffold, or provides a support for a work table or sawhorse.
The attachment comprises a channel having an adjustable web and sidewalls with a reversible angle secured to one sidewall which cooperates with biasing means passing through the channel web and a ladder stile to frictionally lock an elongated member passing through holes formed in the sidewalls as a standoff or roof ridge hook or to frictionally lock an elongated member adjacent a ladder leg as an extension thereof.
