  • Patent number: 7000732
    Abstract: A ladder that has a top portion that has numerous magnets attached or embedded into it. The magnets surround the sides of the ladder top as well as attached to the underside of the top plate. In this way, tools, fasteners, paint cans, or any other metal items can be secured quickly and safely to the ladder top at any time. Moreover, because the device uses thin, flexible magnets, the ladder top is no bulkier than a normal ladder top. Finally, because of the construction, the ladder top is not covered by anything that impairs using the top in a normal way, such as sitting or standing on the top (although this is not a recommended practice, many workers routinely do this as part of their working habits). With this device, workers can fully utilize the ladder as if there was no magnetic holder attached.
