A Framing Rafter Square Attachment. The attachment cooperates with a conventional rafter or framing square to make the repetitive cutting of lengths of framing lumber (such as for blocking) much easier and faster to accomplish. The attachment allows the position of the framing square as held by the attachment to be adjustable so that it can accommodate a wide variety of circular saw fence configuration. The attachment is extendable and retractable so that the attachment has both a compact size for storage, while at the same time being able to accommodate longer cuts. A drag clip may be provided to allow the user to selectively pinch a piece of wood with the attachment so that the pinched piece of wood can then be repositioned for another cut without the user having to set down either the circular saw or the attachment. Finally, the attachment has a subassembly that allows the user to easily cut a piece of lumber to fit a preexisting length or opening.
