Abstract
A ladder stabilizing attachment for a ladder is disclosed. The device is basically made of two or more long variable length stabilizing legs FIGS. (1) and (11) attached to the upper part of a ladder by universal joints FIGS. (9) and (9A), and capable of forming a triangular or multi-angular pyramid with the ladder. The legs can be independently positioned to give greater lateral stability, as well reducing slide out tendency of the ladder base. The foot sockets of the stabilizing legs FIG. (5) are designed to minimize overloading and movement due to ladder flexing. The device is constructed so that it can be built into new ladders, and readily adapted for and fitted to most existing ladders.
