  • Patent number: 6394229
    Abstract: A ladder attachment kit which may be used with outside ladders (10), typically of the extension type, to facilitate access to roofs and to gutters. The ladder attachment kit includes right and left support assemblies (24), each support assembly including a suitably bent support having a first generally straight section (26a), an end section (26b) preferably disposed at an acute angle to the first straight section, and an intermediate section (26c) interconnecting the first section with the end section. Each support assembly further includes a pad assembly (28) which is hinged to the end of the end section of the support so that the pad can lay upon the surface of the roof. The right and left support assemblies (24) are secured to right and left side rails (14, 16) of a ladder by suitable clamp assemblies (22), there being at least two clamp assemblies, and preferably more, for each support, the clamp assemblies slidably receiving the support so that they can be adjusted for roofs of differing pitches.
