Long Tape Measures

With a blade long enough to measure a semi-trailer, these tape measures extend 50 ft. or farther.

Starrett with Calibration Certificate

Image of Product. Front orientation. Tape Measures. Long Tape Measures, Starrett.

When precision measurements are required for quality control or by regulation, use a tape measure that includes a calibration certificate traceable to NIST. The certificate states that the tape measure has passed a test for accuracy, so you can be confident your measurements are correct and consistent.

Coated Steel Blade—A coating prevents the graduations from wearing or scratching off. Made of steel, these blades stay stiff when extended and won't stretch if pulled too hard, so they maintain their accuracy over time. They also keep their shape if dragged over rough surfaces, such as concrete.

Vinyl-Coated Metal Case—Choose metal cases for your toughest industrial jobs, from construction to machining. These cases resist breaking due to hard hits and drops. However, they're heavier to carry around than plastic cases.

The performance of brand-name tape measures without the cost.

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.

Chrome-Plated Steel Blade—Our most durable blades. The hard chrome plating guards them from scratches, wear, and rust. Made of steel, these blades stay stiff when extended and won't stretch if pulled too hard, so they maintain their accuracy over time. They also keep their shape if dragged over rough surfaces, such as concrete.

Fiberglass Blade—These blades bend without breaking, so they're best for measuring curved surfaces, such as silos. The choice for outdoor jobs, they won't rust from water. They also won't conduct electricity when working near conduit and powerlines.

Easy-Carry Long Tape Measures

A favorite among surveyors, these tape measures have a large, rubber-coated handle for a comfortable grip when trekking long distances. Choose them for outdoor and dirty jobs—an open case lets dirt, sand, and other debris fall away, so they won’t clog up the reel. Their blade extends 50 ft. or farther, long enough to measure a semi-trailer.

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.

Coated Fiberglass Blade—These blades bend without breaking, so they're best for measuring curved surfaces, such as silos. The choice for wet environments, they won't rust from water. They also won't conduct electricity when working near conduit and powerlines. A coating prevents the graduations from wearing or scratching off.

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.

Automatic Blade Return—The blade zips back into the case when you let go.

Nonlocking Blade Lock—Pull the blade out and hold it in place between your fingers. These free-moving tape measures are best for taking frequent, small measurements.

Coated Steel Blade—A coating on the blade prevents the graduations from wearing or scratching off.

Rulers for Floors

Take repeated measurements of chain slings and other objects too heavy or too long to lift onto a workbench. These rulers have an adhesive back that permanently sticks to the floor. Made of polyester with a tough polycarbonate coating, they resist ripping even when run over by forklifts. They're also textured, so you can walk on them without worrying about slipping. No need to get up close to read these rulers—their graduations are large and spaced out over a yellow background, making them easy to see.

Long Tape Measures with Automatic Blade Return

Save yourself the effort of cranking the blade back after measuring far distances. These tape measures automatically recoil unless you press the brake or hook the tip onto a stud. A bumper cushions the hook so it won’t slam into the case. With a blade long enough to measure a semi-trailer, these tape measures extend 50 ft. or farther.

Measures Liquid Removed from Tank

Image of Specification. Front orientation. ZoomedIn view. Contains Annotated, MultipleImages. Liquid-Level Tape Measures. Measures Liquid Removed from Tank.

Liquid removed from tank tape measures have a rectangular plumb bob. To find the amount of liquid removed from a tank, lower the plumb bob until it makes contact with the liquid’s surface, then add the measurement from the plumb bob to the measurement from the blade. To determine the amount of liquid in the tank, subtract the liquid removed from tank measurement from the overall tank height.

Chrome-Plated Steel—Chrome-plated steel blades are for measuring dark liquids.

Black Steel—Black steel blades are for measuring clear liquids. They have wear-resistant etched markings.

Stainless Steel—Stainless steel blades are corrosion-resistant. Use them in clear and dark liquids. They have wear-resistant etched markings.
