Made in the USA from 6061 billet aluminum. The through hole for the cable is 1/8” in diameter. It attaches to the motor lug with a 6-32 stainless screw. Cable not included. There are two options to choose from. The "short' version is usually used on .21/3.5cc sized engines and the "tall" version is normally used for .45/7.5cc and larger engines.
