    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.

    Magnetic Rulers

    Measure hands-free without permanently mounting a ruler. These rulers have a magnetic back, so they cling to most surfaces.
    Extra-Flexible Vinyl Plastic
    These rulers are flexible enough to wrap around curved objects, such as sign posts and vehicles, where rigid rulers would snap.

    Magnetic High-Accuracy Rulers

    Take machine-shop-accurate measurements while keeping your hands free. These rulers have magnets on both ends to cling to most metallic surfaces. Also known as machinists’ rules, they have the tightest tolerances we offer. They’re also our most precise, with graduations as small as 1/64", so you can trust them for even the tiniest dimensions.
    All are precision made and etched in the U.S. to meet federal standards. Made of tempered steel for extra strength, they keep their shape even after multiple hard hits and drops, so they'll measure accurately for years to come. Their graduations are deeply engraved and blackened with ink, meaning they won't rub off like printed graduations can.
    Satin Chrome-Plated Steel

    Tough enough to handle most tasks, these rulers are chrome plated to resist rust. Their satin finish reduces glare for easy reading.

    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.
    Stanley LeverLock

    Drop tested to 120 ft., these tape measures still work even if they fall from a 10-story building. A vinyl-coated case and raised metal edges on the front make them extra durable for tackling the toughest jobs, such as construction.

    Don’t let human error slow you down when reading and logging measurements. These tape measures instantly show your exact measurement on the display—no need to count hash marks. Toggle between inch and metric, convert fractions, find the center of workpieces, and record measurements to a screen on the handle, all with the click of a button. They’re also equipped with a laser to precisely align the blade, so you can trust your measurements are accurate every time.
    To calculate, store, and share your measurements, these tape measures connect to an app via Bluetooth. They come with batteries, but you need an electrical cord and adapter (both sold separately) to charge them.
