ABSTRACT:
A pair of attachments for use with ladders constructed with hollow rungs to stabilize the ladder and to protect the gutter. These attachments when used with ladders also provide for a scaffold plank. The attachments when used with a ladder on a pitched roof allows the ladder to be used to access that roofs peak. Previously the ladder would rest on the rain gutter when the user was to access the roof of a building. Previously a work platform had to be built from wood or metal resulting in time consuming construction. Previously when accessing the roof peak of a building a means of providing a positive foothold had to be constructed from rope and ladder or from wood. The present invention provides steel flat bars bent to fit the rung spacing of the ladder with a steel tube welded at each end sized to fit snuggly into the opening of any two consecutive rungs in that ladder. The ladder can now be used to access the roof of a building without resting on the gutter. The ladder can be used as part of a scaffold and to provide a positive foothold when on a pitched roof.
