ABSTRACT:
A scaffolding frame member to be used for supporting scaffolding planks along the side of a building structure and adjacent the roof thereof. Each member is basically comprised of four folding parts, a roof member, an upright channel, a turnbuckle connected between the roof member and channel, and a bottom brace member. All four members fold together to form a compact unit for easy storage and transport. The frame member is mounted to a structure by first securing the roof member to the roof structure or frame with the channel and bottom brace hanging over the structure side. The turnbuckle mechanism can then be tightened between the roof member and suspended channel member to pull the channel member inwardly and press the bottom brace firmly against the structure wall. The bottom brace may then be secured to the wall.
