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.

Vernier Scale with Calibration Certificate

Our most precise diameter-measuring tape measures. Wind the blade around your object until the top scale aligns with the bottom vernier scale, then add the values together to find your diameter. These tape measures include a calibration certificate traceable to NIST, so you can be confident your measurements are correct and consistent.

Blue Blade—White markings pop against the blue background, so you can read these tape measures in dimly lit areas.
