2 aluminum rings that will work with the EML30 & EML35 Coil Gun. They can be used over and over (as long as you don't lose them!)

These rings are cut from aluminum tubing (1" outer diameter, ¾" inner diameter) and then deburred. You can get this tubing from a local hardware store and cut rings yourself, or we offer them here as a convenience if you do not have the setup for cutting & deburring aluminum tubing.
