The diameter of a circular object, like a tree or a pipe, is easily measured using a Keson diameter tape. The tape is calibrated in units of 3.14 (pi) inches. The tape is actually measuring the tree or pipe’s circumference, but the units on the tape are adjusted by pi enabling you to get a diameter by wrapping this tape around a circular object. Our PD618 has a stainless steel case which features a reflective surface and textured rubber grip to keep the tape from slipping.
The KESON ST18M100Y 100 ft/30m Tape Measure is the perfect tool for measuring long distances. The tape measure has 16 in stud markings, making it easy to mark measurements on walls and other surfaces...
