  • Ladder guide assembly for a scaffolding
    Patent number: 5992564
    Abstract: A ladder support device is secured to a scaffold by two base arms. At one end of the base arms the device forms a "channel" in which the ladder can move vertically but not horizontally. This secures the ladder so that it cannot fall away from the scaffold or to either side. In addition, it allows the scaffold to be raised or lowered without having to detach the ladder from the scaffold.
