LCB Series Copper Compression Lugs Panduit LCB Series Copper Compression Lugs are code conductors with one-hole and long barrels. The long barrels maximize the number of crimps and provide premium wire pull-out strength and electrical performance. These enclosed barrels prevent corrosive material from entering the barrels when used in harsh environments. The color-coded barrels are tin-plated to inhibit corrosion and are marked with Panduit and specified competitor die index numbers for proper crimp die selection. The LCB copper compression lugs are UL listed and CSA Certified to 35KV and temperature rated to 90°C (when crimped). These lugs are also UL Listed and CSA Certified for wide wire range-taking capability when crimped with Panduit® Uni-Die™ dieless crimping tools.
