📐 Elevate your craft with the Big 12 — the only square you’ll ever need!
The Swanson Tool Co S0107 Big 12 is a 12-inch speed square crafted from heavy-gauge aluminum alloy with a matte finish to prevent glare. Combining seven essential tools in one—framing, try, miter, protractor squares, saw guide, stair gauge, and out-of-square corner finder—it’s designed for precision and durability. Featuring 1/4 and 1/2 inch spaced notches for easy scribing and black gradations for clear reading, it includes the patented layout bar and a 62-page Blue Book guide for expert roof and stairway layouts. Perfect for professionals seeking reliable, multi-functional measuring tools.
