Durability meets precision with the Shinwa 7″ Stainless Steel Rafter Square.
Dial in your framing accuracy with the Shinwa 7″ Stainless Steel Rafter Square. Crafted in Japan by Shinwa, this layout square brings laser precision to post-and-beam joinery and roof layouts. Unlike standard aluminum squares that wear out, this tool is cut from high-grade stainless steel. The slim profile stops pencil gaps, giving you tight, clean lines every time.
In a class of its own, the Shinwa 7″ Stainless Steel Rafter Square puts master craftsmanship with precision layout tolerance in your hands.
Take advantage of these key features:
-
Ultimate Jobsite Durability: Designed to survive drops from roofs and heavy job boxes without losing its 90-degree accuracy. Made of rust-resistant stainless steel, it stands up to rain, sun, and daily jobsite weather.
-
Tight Tolerances for Timber Joinery: Built to strict Japanese standards. Accuracy you can count, unlike a cheap square from a big box store.
-
Eliminates Pencil Shift: The ultra-thin 1/16″ profile sits flush against heavy timbers. This stops your pencil tip from jumping away from the edge.
-
Versatile Right-Angle & Pivot Layout: The triangle shape provides instant 90° cross-cuts, 45° miters, and a pivot point. Quickly set plumb cuts, seat cuts, and pitch angles.
-
Laser-Cut Precision Stainless Steel: Made from rust-resistant stainless steel. It features etched Imperial marks that will never rub or scratch off.
-
Versatile Rafter Tables: Includes common rafter tables, hip tables, pitch scales, and degree marks in fractional inches for fast math.
