ABSTRACT:
A series of horizontally spaced tubular metal frames each include a pair of vertical short and long leg members rigidly connected by an inclined support member having a projecting upper end portion. The leg members are removably connected to the top ends of vertically aligned legs of a tubular metal scaffold assembly positioned adjacent a building. The inclined support members receive connector members connected to the building roof or ridge members connected by horizontal support members and supported by vertical posts resting on the roof or floor. A flexible light transmitting plastic film is supported by the inclined support members and ridge connector members to enclose the frames and scaffold assembly, and the film has an edge portion clamped to the roof or floor.
