Use our Thin Beam Square to mark and cut thin wood and plastic. The extra-thin profile of the beam allows the blade to stay in close contact with the surface of the workpiece, so scribe lines and knife cuts will be super accurate (see the image of our Thin Beam Square as compared to a traditional square at left). Works on sheet and strip stock up to 4 inches wide and as thin as 1/16 inch. Made of ground steel to Micro-Mark specifications.
