ABSTRACT:
A device which is easily attached to the stiles of any ladder. This highly reliable device creates a steadfast ladder, removing the fear of the ladder flipping over or slipping out from under. This device is created in such a manner as to be attached to any ladder and also having a clearance to allow for any shoes attached or to be attached to the ladder's base. Ground penetration is easily achieved by the slike's ability to rotate. The design of the device allows ground penetration to any depth, making allowances for obstructions. Safety is achieved by the device's ability to stabilize the ladder's lower end. The handle lies flat against the ladder's stiles creating a self-contained unit that is out of the way when not in use.
