Two-hole long barrel compression lug for terminating 500 MCM copper conductors to 1/2-inch studs. Engineered for power distribution, switchgear, and industrial panel applications where dual-bolt mounting prevents rotation under fault conditions. The long barrel maximizes contact surface area for full-tension crimps, while the chamfered cable entry eases conductor insertion.

FAQ
What crimping tool and die are required?
Use die index I-87. Verify tool compatibility with your crimping equipment manufacturer's die chart before installation.
Why choose a long barrel over a short barrel lug?
The 2.25-inch barrel length provides greater surface contact with the conductor, distributing compression force across more area for improved mechanical pull-out strength and electrical conductivity.
Is this lug rated for 35kV applications?
The voltage rating extends to 35kV; however, actual installation voltage class depends on insulation, spacing, and enclosure ratings per NEC and local utility standards.
