For woodworkers who demand precision, this Woodpeckers 49.5-inch rule is a game-changer. Machined from aircraft-grade aluminum and anodized red, it's incredibly straight, heavy, and lays flat on your workpiece. One side has a standard left-to-right scale, while the other features a centering scale with '0' in the middle – perfect for finding the center of boards or spacing hardware evenly. The scales are laser-engraved with an accuracy of ±0.004 inches, and the 30° beveled edges reduce parallax error. Finger grooves make it easy to handle, and there are threaded holes on both ends for optional accessories like a hook stop, protractor head, or rule stop. Made in the USA with top-notch craftsmanship, this ruler is built to last a lifetime in your shop. Whether you're marking cuts, checking for square, or laying out joinery, it's an essential tool for serious craftsmen.
