Speed Square, 12"
This pocket sized square incorporates the features of the framing square, tri, miter, and
protractor squares. Common rafter and hip/valley rafter scales permit
one-number references for all cuts. The square is merely rotated to the
proper roof pitch value on either scale to assure the correct angle
cut. The slot along the scales will accommodate an adjustable locking
pin for repetitive cuts using any 1/4-inch bolt and nut.
