Definition of "girt"

There are various ways of tying rafters to sidewalls, and the choices may vary depending on roof pitch. One of the most common is the use of “birdsmouths” cut into the rafter. A notch is cut into the rafter so that the rafter bears down flat upon the doubled top plate of stick framing, or upon the girt in heavy timber framing.
