Pocket Tape Made for Curves!

“It's great. I use it for measuring the diameter of couplings and shafts for work. Exactly what I wanted so I don't need to carry around large calipers or eyeball across a tape measure during alignments.” -Leo F. 

Why Get Our Magnetic Pi Diameter Circumference Tape Measure?

✅ Made for Curved Objects: Standard tape measures are not able to wrap around circular shapes or show diameter like wood log or steel pipe. This tool uses a flexible steel tape with both diameter and circumference scales to give fast, clear readings on round materials.

Clear Dual-Scale Display: The tape shows standard length on the top side and precise diameter on the underside, with easy-to-read markings down to 1/16 inch and 1/100 inch, as well as millimeters.

✅ Compact Design: This pocket-sized tape weighs just over 3 oz made for DIYers and crafters. It has a strong magnet for quick storage, a brake to control retraction, and a loop end for easy wraparound measuring.

📓FREQUENTLY ASKED QUESTIONS

Q: How do I properly use this to get a diameter reading?
A:
Wrap the flexible tape around the object until it's flush. The zero mark indicates where to read the diameter on the underside scale.

Q: Can I store this on metal surfaces like a toolbox or ladder?
A:
Yes, the magnetic case sticks securely to most flat metal surfaces for easy access while working.

Accurate Diameter Reading

Finally, something that shows diameter directly. I don't have to calculate from circumference anymore.
