The LCAX1/0-38-X Tin-Plated Copper Compression Lug, one-hole, standard barrel, has color-coded barrels marked with Panduit and specified competitor die index numbers for proper crimp die selection. The generously beveled wire entry prevents bent back strands when inserting the conductor into the barrel. An inspection window aids to visually assure full conductor insertion, and the tin-plate material helps to inhibit corrosion. UL Listed and CSA Certified.
