Two Hole Long Barrel Lugs
Two hole long barrel lugs have a second hole for additional strength during the vibration of equipment. They also have a long barrel for additional support during the application as well. When a machine is loud and it shakes the lugs can vibrate and create a loose connection. Using two hole lugs will help limit such things from happening.
The two hole long barrel lugs on this page are rated from 600 volts up to 35,000 volts. They have a temperature rating of 90°C and they are both UL and CSA approved.
