Abstract
An apparatus for holding a first rectangular board in a predetermined orientation to a second rectangular board. A holding apparatus is disclosed comprising a corner member having a first flat edge substantially corresponding in dimension to the width and thickness of a squared edge of the first board and a second flat edge located at a predetermined orientation from the first flat edge also corresponding in dimension to the width of the squared edge of the second board. Each flat edge of the corner member has an elongated protrusion, in the shape of a wedge, extending outwardly at a midpoint region. The protrusion engages a correspondingly formed tapered slot in the squared edges of the first and second boards. Bonding means is applied to the flat edges and protrusions to engage the squared end and tapered slot of each board.
