A ladder stabilizling attachment for a ladder is disclosed. The device is basically made of two or mare long stabilizing legs (1) and (11) attached to the upper part of a ladder by universal joints (7), and capable of forming a triangular or muni-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 (3) of the stabilizing legs 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 easily adapted for and fitted to existing ladders.
