ABSTRACT:
A roof scuttle safety railing system is provided for an existing or new roof scuttle which railing may be installed on the roof scuttle by unskilled labor without compromising the integrity of the weather seal of the roof scuttle. In one embodiment, pivotal corner brackets are secured to the capflashing of a roof scuttle with the vertical members of the safety railing being inserted in openings in the brackets. In another embodiment, an elongated bracket is used along two opposed sides of the roof scuttle which brackets are firmly held against the outside walls of the roof scuttle by tie rods, a strap or a cable. The elongated bracket has vertical openings at its distal ends for securing the vertical members of the safety railing and horizontal openings or slots for the tie rods, straps or cables. A hinged gate is also provided which preferably has a self-closing hinge.
