Abstract: A nailing anchor for use in fixedly attaching a series of parallel wooden boards to a transverse joist. The member has two flat, horizontal tabs each positionable between one of a pair of adjacent boards and the joist. The tabs are fixedly attached to a flat spacer body and extend perpendicularly therefrom in opposite directions. A hole in the one tab allows the anchor to be nailed to the joist. An elongated slot in the spacer body allows the anchor to be toe-nailed through the one adjacent board into the joist. A flat, triangular point depends perpendicularly from an upper edge of the spacer for fastening the one board to the spacer body.
