The Big 12® is seven tools in one: a framing square, try square, miter square, protractor, saw guide, stair gauge and out-of-square corner angle finder. It’s constructed of heavy-gauge aluminum alloy. It does not include the black gradations or the Layout Bar and hardware of the S0107 Speed® Square.
