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