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.

Go/No-Go Outside Diameter Gauges with Calibration Certificate

Dial Indicator
(Sold Separately)
With a calibration certificate traceable to NIST that says they've passed a test for accuracy, you can trust these gauges to confirm if your object's outer diameter is within tolerance. They're also known as snap gauges because they snap onto rods, shafts, and other cylindrical objects. To maintain their accuracy over time, they have a hardened steel frame and spindle that withstands flexing and temperature changes.
Attach dial indicators to measure the difference between your part’s actual diameter and the expected diameter. They also come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

(Sold Separately)
Also known as snap gauges for how they snap around rods, shafts, and other cylindrical objects, these gauges quickly check if an outside diameter is within tolerance. They have a hardened steel frame and spindle that stand up to flexing and temperature changes, so they stay accurate over time.
Attach dial indicators to measure the difference between your part’s actual diameter and the expected diameter.
