ABSTRACT:
A universal apparatus for attachment to each corner of a scaffold vertical member and having toe board holding flanges attached thereto for receiving the ends of toe boards therein. The bracket is of a type which can be opened by a hinge and disposed around a vertical scaffold member and then locked in place whereby it has universal application to almost any standard scaffold structure. The toe boards themselves are typically constructed of lumber which would be on the construction site anyway, such as 2".times.6" members which can be cut to a desired length.
