TDP659 - 7-Inch Aluminum Rafter Layout Square

Essential Layout Tool for Welders and Fabricators

While often associated with carpentry, the Techniweld Aluminum Rafter Angle Square is a secret weapon in the welder's arsenal. When you are fitting up frames, laying out cut lines on plate, or checking the squareness of a tack weld, this tool is indispensable. The solid aluminum construction makes it tough enough to survive the welding shop floor—it won't rust when exposed to coolant or moisture, and it is non-magnetic, meaning it won't get covered in grinding dust and steel filings like a steel square would.

Speed and accuracy are key in fabrication. This square allows you to quickly mark perfect 90-degree cut lines and 45-degree miters on angle iron, square tubing, and flat bar. The built-in protractor scale is incredibly useful for laying out custom angles for braces and supports without needing a separate bevel gauge. The thick lip of the square hooks securely over the edge of your workpiece, allowing for one-handed marking so you can keep your other hand free for your soapstone or scribe.

Furthermore, the square acts as a sturdy saw guide. If you are using a handheld plasma cutter or an oxy-fuel torch, you can drag your torch tip along the edge of this square (keeping a safe distance to avoid melting the aluminum) to achieve straighter manual cuts. Lightweight and compact, it fits easily in your back pocket or tool bucket, ensuring you always have a reliable reference for square and plumb right at your fingertips. Upgrade your layout game with a tool that bridges the gap between woodworking precision and metalworking durability.
