Drawing straight, accurate lines can be challenging when relying on a tape measure and a scrap of wood as a straight edge. Now there"s a better way, the new Woodpecker T-Square. Whether working off a factory cut edge or not, the Woodpecker T-Square will help you draw straighter, more accurate parallel lines in less time than you can imagine. In an instant, you can move your pencil from 3" off the edge to 12" and be dead-on without the need of a tape measure. Each Woodpecker T-Square consists of a precisely machined, laser engraved, aluminum blade perfectly fitted to a solid, billet handle with two support lips to prevent tipping and a perfectly machined edge for true squaring. The two critical parts are secured together with six precision socket screws. This arrangement delivers top notch performance yet still allows for replacement of damaged blades. The blade itself has precisely spaced 1MM holes drilled every 1/16". Stick a pencil in the hole, slide it along your work piece and presto, a perfectly spaced line accurately following the stock edge. The outer edges are machined to a 30 degree bevel for easy reading and laser engraved scales for measuring. Additional holes are machined on exact 1" centers for marking shelf pin locations. Two different sizes are available, 12" and 24". The 12" size is ideal for work with solid lumber and smaller cabinet parts. The 24" is better suited for work with sheet goods. We take great care in making these T-Squares so you can be sure that every marking is laser perfect and every hole is accurately spaced. In fact we make these tools on machines accurate to fractions of a thousandth of an inch. Accurate to .001", guaranteed for life. And like all the tools Woodpeckers makes, they"re machined in our shop, right here in the U.S.A. Each T-Square comes in its own fitted, wooden, wall mountable case so you can be sure it"s safely stored yet always in sight.
