This structural detail shows framing for a roof deck opening supported by roof joists or wide flange beams. The design is based on a six-foot maximum opening dimension and a six-hundred-pound load over the opening. L4x4x3/8 and L4x4x1/2 structural angles are placed between the roof joists typically around the perimeter. Larger openings or heavier loads require submission to the structural engineer for review.
