Something that causes a lot of confusion among users of seaming machines like Cinch, is whether they should use metal springs or plastic spirals, depending on whether their machine has a square or round hole.
The answer is very simple, the Cinch crimpers are compatible with the metal spring and the plastic spiral, as long as they have a 2:1 pitch. What makes the difference is the finish of your project and its functionality depending on the product you chose.
I hope this information is useful for your business.
