Certified High-Accuracy Diameter Tape Measures
 |  Diameter Inches |
 Diameter Centimeters |
Accurately measure diameter. These tape measures include a calibration certificate traceable to NIST stating they have passed a test for accuracy. Wrap them around circular items to determine diameter without the need for calculations. They have wear-resistant etched markings.
Stainless steel blades are corrosion resistant.

Diameter Tape Measures
Also known as tree tapes, wrap these tape measures around circular items to determine diameter and measure circumference without the need for calculations. The blade is chrome-plated, vinyl-coated, or painted to resist scratches, wear, and corrosion, and the case is coated for scratch resistance.
Chrome-plated blades are more durable than vinyl-coated blades.
Pointed-hook tip grabs the edge of an object or drives into wood.
