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.

Build-Your-Own Wire, Cable, and Cord Length Measurers

Combine a counter, feeder reel, coiler reel, and stand to create a wire, cable, and cord length measurer.

Counters measure material as you thread it through the internal wheels. These counters add and subtract. Mount them on a pedestal or floor stand (sold separately). Urethane-coated wheels are for PTFE-coated wire and fiber-optic cable.

Feeder reels hold material before it's threaded through a counter. Wind material around adjustable pins on the reel, or place spooled material on the 1/2" diameter spindle.

Coiler reels gather material once it has passed through a counter. These reels have a hand crank and collapse for storage.

Wire Length Measurers

Bench Mount

Floor Mount

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.
