ABSTRACT:
A new Bat for measuring and facilitating marking the interior surfaces of an angled work piece, such as angle iron, which cannot be measured or marked by a conventional square because of arcuate corners and formed edges. The inventive device includes a first plate having a slanted edge, a first member secured to the first plate, a second member secured to the first member forming a syncline shape or V-shape which receives the arcuate corners and formed edges, and a second plate secured to said second member where the second plate is orthogonally aligned with respect to the first plate.
