Johnson CS18 400mm x 600mm Metric Aluminum Framing Square

Johnson’s 400mm x 600mm metric framing square is everything a builder needs to get the work done quickly, efficiently and accurately. It includes graduations in 2mm increments as well as metric conversion tables for rafter work. And reading those graduations and conversion tables is especially easy thanks to Johnson’s laser-etched EZ Read text. This framing square’s aluminum construction makes it conveniently lightweight while also keeping the tool safe from rust.
