  • Hatch safety railing system
    Patent number: 6681528
    Abstract: A roof hatch safety railing to help prevent a person from accidentally falling through an open roof hatch while walking on a roof. The safety railing will comprise a top rail sufficiently high to prevent a person from falling over the railing. A mid-rail will also be located so that a person cannot accidentally fall under the top rail. The safety railing will be hingedly attached to the cover of the roof hatch as well as mounted to brackets which have been inserted into the coping of the base of the roof hatch. The safety railing will not interfere with the normal operation of the roof hatch and may be modified to accommodate various types and sizes of roof hatches.
