Abstract
A device for attachment to a ladder which enables the upper end of a ladder to be spaced from the wall of the building, span windows and/or rest on a slant roof and thus span the gutters. The device also acts as a stabilizer bar or tube to prevent slippage of the ladder laterally, gives greater stabilization to the ladder, and almost automatically positions the ladder at the correct angle of inclination away from the lower wall of a building, and generally promotes a greater margin of safety. Also, the device is readily separable after use for small compact storage.
