  • Ladder inclination indicator
    Patent number: 5956855
    Abstract: A ladder inclination indicator has a transparent thin-walled body shell defining a rearwardly open recess containing a pivot pin supporting a gravity actuated pointer. A keeper plate forms a partial closure for the recess and carries a label which cooperates with the pointer to indicate a position of ladder inclination. Layers of pressure sensitive adhesive adhered to mounting flanges on the body shell secure the device to the side rail of a ladder.
