Johnson’s 16″ x 24″ framing square is everything a builder needs to get the work done quickly, efficiently and accurately. It includes graduations in 1/8″, 1/10″, 1/12″ and 1/16″ as well as octagon scales, rafter tables, brace tables and board foot tables, making it useful for any number of different jobs. And reading those graduations and conversion tables is especially easy thanks to Johnson’s thermal-bonded EZ Read text.
