What is the Cut-off Mark ?
A – The Cut-off Mark is only a reference dimension that will show you about how much tubing you will need to make the project. This mark is approximate, so you should only use this mark as a guideline to estimtate how much tubing will be required to make your project. I would not cut the finished end of the tube until all of the bends have been completed and you are certain that you have enough tubing left to finish the final leg of your project. It is always better to have a small amount of extra tubing on the last leg of the project that can be trimmed to fit during the final assembly process.
