Collar to allow marking 360 degree around straight tubing.
These collars also feature thru holes as well as marks every 22.5 degrees to allow for marking rotational clocking marks. i.e-22.5, 45, 90, 180... Helpful when placing tube in a bender for rotation.
Friendly reminder tube is measured by the "OD" or outside diameter. Make selection based on the size of tube you are working with.
Please contact to request additional sizing you may not see.
