    About High-Quality Rulers
    industrial info icon

    What separates a throwaway ruler from one you’ll keep for decades, which type is best for everyday use, and how to compare materials.

    Adhesive-Back Rulers

    Free up your hands when measuring length over and over—no more lining up rulers or tape measures. These rulers stick to everything from toolboxes to lathe beds for a permanent measuring guide.
    Extra-Flexible Steel
    Image of Product. Front orientation. ZoomedIn view. Rulers. Adhesive-Back Rulers.
    Combine the flexibility of plastic with the strength of metal. These rulers are bendy enough to conform to curved surfaces and durable enough to resist scrapes and scratches.

    Rulers

    Your go-to rulers for everyday measuring. Whether metal for durability or wood for a classic feel, our rulers measure up to most tasks, from woodwork to textiles to rough machining.
    Lightweight Aluminum
    Image of Product. Front orientation. ZoomedIn view. Rulers. Rulers, Lightweight Aluminum.
    Our economical option. These rulers are about as lightweight as plastic rulers, so they're convenient to carry from site to site. Although light, they're not flimsy—they resist snapping if knocked around in your toolbox. Plus, they'll keep their bright finish if frequently rinsed.
    Length—For easy handling and storage, 4 meter rulers come in two pieces that line up to create a complete ruler.

    Tape Measures

    The best of the best tape measures for everyday tasks—from Stanley to Lufkin to Milwaukee. Built to last, these tape measures have a coating on the blade that prevents the graduations from wearing or scratching off. Their durable plastic case won't crack when tossed into tool bags or dropped on the ground.

    Flexible Tape Measures

    Image of Product. Front orientation. Tape Measures. Flexible Tape Measures.
    Whether you're finding the length of winding cables or the circumference of drive belts, these tape measures accurately measure around corners and curves. Made of coated fiberglass, they're soft enough to wrap into a coil, yet strong enough that they won't stretch, so they stay accurate over time. Brass caps prevent the ends from fraying and tearing.

    Measure distance, level objects, and draft circles with one tool. A jack of all trades, these tape measures include a vial level and a compass for drawing circles up to 20 ft. in diameter. You don’t have to crimp the blade to measure inside drawers and other objects—a top window shows the length from the tip of the blade to the back of the case.

    Digital Linear Scales for Saws

    Cut with confidence—these scales use sensors to precisely measure the cut length for you. This makes them both more accurate and faster than traditional linear scales that use a tape measure. Before each cut, slide the stop until you see the right length on the display. These scales are often mounted to chop and miter saws to slice bars and sheets into consistent lengths.

    Scale with Digital Touch Screen Display

    Scales with automatic positioning add an extra level of precision thanks to a stop that you program instead of moving yourself. Input your desired cut length and the stop will automatically slide to within ±0.008" of that target.
    Touch-Screen Display—Scales with a touch screen display let you program a series of cuts. Save frequent cut jobs or upload them from a USB flash drive.
