Abstract: A carpentry measuring tool including two arms pivotally connected at adjoining ends thereof. The two arms are angularly adjustable with respect to one another, and are adapted for determining the angle formed between the interior portions of intersecting horizontal and vertical surfaces of a door or window frame. One of the arms is provided with an extendable slide portion on the end thereof and is adapted for measuring the distance between interior portions of opposed surfaces of the frame. The distal end of the slide portion contains a spring biased heel which may be retracted for removal of the one arm from within the door or window jam. The angular relationship of the two arms and the length of the one arm may be fixed so that these measurements may be transferred to a door or window which is to be hung in a measured door or window frame. Slidable clips or plates along the exterior portions of the other arm are particularly suited for use with doors and are adapted to be extended from the other arm to permit proper alignment of the measuring tool along one edge of the door for accurate marking of the desired dimensions thereon and for an automatic predetermined reduction of the door width.
