Two Hole Short Barrel Lugs
Two-hole compression lugs have a second hole for additional strength during the vibration of equipment. 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 short 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.
