Success in the workshop depends on careful machinery set up, accurate layout and consistently checking your work during assembly. All three jobs call for a quality square, and here is the one that established Woodpeckers as a premier layout tool manufacturer, the 1281 Precision Woodworking Square. What separates Woodpeckers squares from the rest is our one-piece central core, milled from the most stable aluminum plate made in the world. The central core gives the 1281 an accuracy and stability not found in competitive tools.
