Measure sheets, rolls, and strips using these wheels and their attached counters.

Aluminum wheels are for high temperature processes and coarse materials such as sandpaper. The surface is knurled for good contact.

Plastic wheels are for smooth materials such as paper and cloth.

For technical drawings and 3-D models, click on a part number.

Feed wire through the wheels inside the included counter to take measurements. The counter adds and subtracts. Wind your wire around adjustable pins on the feeder reel, or place spooled wire on the 1/2" diameter spindle. Gather it on the coiler reel once it has passed through the counter. Coiler reels have a hand crank and collapse for storage.

Urethane-coated wheels are for PTFE-coated wire and fiber-optic cable.

Roll these wheels along a surface to measure distances up to 99,999 feet. Choose 36" circumference and larger wheels for measuring uneven surfaces.

Style E operates on a nonreplaceable battery with a minimum 10 year life.

Keep your phone in your pocket and your hands free—these smartwatches perform a variety of functions on your wrist. They connect to Apple and Android phones via Bluetooth, informing you when calls, texts, and other notifications arrive. Designed for harsh environments and rugged use, they meet military standards for resistance to hot and cold temperatures, shock, splashes, and submersion in up to 100 meters of water. These watches have a compass and GPS for tasks such as navigation, tracking and saving location coordinates, and calculating the area of a location by walking the perimeter. With weather and elevation monitoring, you can set the rate of barometric pressure change that will trigger a storm alert. These watches track health and fitness metrics over time, including heartrate, blood oxygen levels, and exercise. They have a solar battery in addition to a rechargeable lithium-ion one to extend the time between plug-in charging.
