ABSTRACT:
A device and method for improving the mobility of a ladder. The device includes slide pads that attach to the bottom ends of a ladder's rails. In this manner, the slide pads are interposed between the bottom of the ladder rails and the ground when the ladder is erected. The bottom surface of the slide pads have a lower coefficient of friction than do the bottom ends of the ladder rails. Accordingly, the presence of the slide pads at the bottom of the ladder rails makes the ladder rails easier to slide over the ground.
