Abstract: A support for a railing of a roof hatch having a coaming has an angle body with a first elongate member and a second elongate members that is perpendicular to the first elongate member. First and second brackets extend inward from the first and second elongate members, respectively. Each bracket has a coaming-receiving portion that is sized and shaped to directly engage the inner surface, upper surface and outer surface of the hatch coaming, and a flashing covering portion that is sized and shaped to receive the flashing. The bracket engages the coaming such that the angle body is supported laterally adjacent to the flashing of the coaming. One or more post supports connected to and extending outward from angle body.
