Allows for accurate 360 degree marking around mandrel bent tubing. Collars are 15 degree so when used in conjunction with the Mandrel Marking Tool it allows you to split the 10 degree marks. Also has rotational marks on the face every 22.5 degrees. They are designed in a way that as you slide them along the bend they stay in line with the CLR of the bend to fine tune a cut to get perfect fitment on your project!
Not intended for straight tube. Those can be made available upon request.
Size when ordering is OD of tubing x Center Line Radius of the mandrel bend.
