Abstract
A generally triangular hook-on scaffolding support is formed by the alignment of a horizontal elongated top member over an angled brace and a vertical brace. A short section of serrated angle iron affixed transversely to one end of the top member abuts to inside surfaces of an opened stud wall and in conjunction with a wedge bracket and wedge board provides a strong pressure fitting for securing the scaffold in a stable position outside or by reverse attachment inside a building under construction. Another short angle iron section affixed to the distal end of the angled brace is adapted as a brace foot to engage the lengthwise edge of a horizontal board, either the bottom sole plate of the wall frame or a board nailed between studs, to provide base support for the scaffold. The scaffold can therefore be positioned at any height along the opened framed wall without the use of ground level support, nailing the hook-on scaffolding support to the framed wall, or assemblage of accessory parts.
