(EN)

This invention relates to a device for attachment to ladders which will enable them to securely anchor to the peak of a roof quickly and easily, while increasing safety for firemen cutting ventilation holes near the peak of the roof. The attachment for roof ladders allows the firemen to stand on a support directly below the roof area where the hole is cut. The invention can be folded into a compact bundle for storage and transportation, and is light in weight.
