Jackson Safety Pipe Marker Centering Tool, Curv-O-Mark Standard 6, 14775 - Use to measure Pipes 0.5 and Up, Standard 4 Y-Type Head, Adjustable Dial Set Level

This is a great product, and well made!

Ease of use and accuracy

Exactly what I ordered.

I ordered the same one Ive used for years. Always been pretty reliable, seems to be more accurate lining it up with the top notch versus the bottom but Ill verify the true accuracy when I find the degrees of an arc with actual measurements on a pipe and update ASAP.

Works great for HS Mud Motors

I think they could do better The lines/notches dont line up very well. The punch falls right out so its use 2 hands or go looking for it. Broke the bubble vial a week in Anybody know what size it is

needs to have a magnet inserted to help it stand on its own.

Saves lots of time...

We perform geotechnical instrumentation throughout the United States. This tool speeds our process up dramatically and is as accurate as some other pain staking procedures. Very good accuracy, other models will perform better but the price difference does not warrant the cost.
