The Conversions Tech CT-LB250-12 is a one-hole long-barrel compression lug for terminating 250 kcmil Class B stranded copper conductors in power distribution, switchgear, transformer, motor, and grounding applications. The barrel is manufactured from seamless high-conductivity electrolytic copper tubing and electro tin-plated for low contact resistance and long-term corrosion protection. The extended barrel accepts two crimps for maximum pull-out strength, and the chamfered entry eases conductor insertion. Each lug is stamped with conductor size, die index, and color code for correct die selection.
