Abstract:
A ladder safety device (100) is usable for holding and stabilizing a ladder in a safe and stable manner while being used, by way of securing a ladder relative to continuous horizontal guttering at the edge of a building. The device (100) locks to the gutter by way of locking jaws (130), (160) and is secured to the side rail of a ladder by way of an adjustable locking bar (140).
