Woodpeckers Precision Triangles, 12 in. / 18 in. / 300mm / 450mm

Large Triangles for Accurate Layout Work in Larger Projects

Woodpeckers took the form factor of the familiar carpenter's square, and enlarged it to sizes suited for large-scale furniture and cabinet work. However, Woodpeckers new Precision Triangles aren't stamped out like big-box store carpenter's squares. Each one is precision-machined to the same tolerance Woodpeckers uses when making its famous Precision Woodworking Squares.

Here's an 18" reference with both 90° and 45° angles where the maximum allowable deviation is less than half the thcikness of a typical human hair.

Woodpeckers added a base to one edge of the square for convenience when doing layout work, but if you want the sqaure to lie flat, the base comes off with just a few machine screws. With or without the base, you have a highly versatile and extremely accurate tool that will elevate your layout work, assembly checks, and machinery setups.

When you're using the triangle as a giant carpenter's square, the base gives you a positive reference to your workpiece edgejust hook it and mark. It also acts as a foot when you want to check a vertical face, like the inside of a cabinet. And, nothing could be handier when you're setting up a track saw table.

But there are times when you want a 90° or 45° reference without a shoulder, for example, checking the inside of a drawer for square, or setting the miter gauge on your table saw. When you want it flat, just spin out the socket head cap screws and the base comes off, leaving you with a triangle that lies perfectly flat.

Woodpeckers machines the Precision Triangles from cast and ground tool plate aluminum - the most dimensionally stable aluminum available. We treat the surface for improved wear resistance and to give the triangles our familiar Woodpeckers Red" color. The two 90° edges are laser engraved with graduations in your choice of inch or metric. The resulting white-on-red scale is easy to read, even for older eyes or poor lighting conditions.

Choose from 2 sizes, or order the set. Either the 12" or 18" will make a great addition to your shop. They're available with or without a wall-mountable storage case.  If it's too hard to decide which size you want, they're available as a setalso with or without storage case.

Like all Woodpeckers products, the Precision Triangle is precisely machined and carefully inspected in the USA in its Stronsgville, Ohio facility just south of Cleveland.
