ABSTRACT:
A suspended scaffold, which hangs from the wall plate within a frame structure, has two hangar brackets attached to the wall plate. Each bracket has an outer retainer bar for insertion between the wall plate outer face and an adjoining sheathing panel. A cooperating clamp portion has a cross-bar lying upon the top face of the wall plate and a downwardly extending load bar and extension piece having a forwardly projecting braced foot which carries the platform lumber. Pivotal links connecting the clamp portion with the extension piece enable clamp opening/closing, and include disabling and safety locks that are engaged by the extension piece. The braced foot portion, which has a plank-retaining toe, can be folded up when free of platform lumber.
