About High-Quality Rulers

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 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

Don't fumble awkwardly with a thumb button. These tape measures have a release lever on the bottom that falls naturally under your fingers. Squeeze it to zip the blade back. With a bright orange case, these tape measures are easy to spot in toolboxes and on busy bench tops.

Automatic Blade Lock—Extend the blade and it locks in place automatically. These tape measures are especially useful for solo jobs since they free up your hands for other tasks.

1/8" Numeric Graduations—The graduations are labeled every _1/8" for fast reading. No need to count individual hash marks.

Lufkin Shockforce Series

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. Plus, the blade is extra wide, so you can extend it at least 11 ft. before it collapses. Loop a lanyard into the tether point to secure these tape measures when working from catwalks and other heights.

Replacement Blades

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.

Diameter-Measuring Tape Measures

Wrap around duct, pipe, and other cylindrical objects to find their diameter without complex calculations. These tape measures are ideal for already mounted objects since you don't need to take your system apart. Also known as tree tapes.

Standard Scale

Take math out of the equation completely. After wrapping the blade around an object, find the number that overlaps with zero—that's your diameter.

Manual Blade Return Type—Guide the blade back by hand or using the wheel on the side of the case.

Digital Protractors with Level and Laser

A dot laser extends the working distance 200 feet beyond the tool length. This tool has two digital displays that invert when turned upside down; one shows the base angle and the other shows the moveable arm angle. It also has a lock to hold the arm in position, a hold button that freezes the display, auto shutoff, and 1/4"-20 threads for connecting to a tripod.
