ABSTRACT:
A template square (10) for marking a length of floor joist lumber to be cut into a floor joist board for mounting to a support beam in the center sill support framework of a building. The template plate (10) comprises notches (26,27), slots (31), flange pieces (14,15), and tension springs (16, 17). The flange pieces (14,15) mount within the slots (31) to form a flange along the upper portion of the template square (10) so that the template square can be aligned on the floor joist lumber with the flange abutting the top edge of the lumber. So arranged, a cut-line can be traced along a side edge (22,23) of the template square (10) with the notch (26,27) spaced a predetermined distance from the flange.
