Feature	Benefit
Barrels seal on cable insulation	Provides improved corrosion resistance over unsealed terminal lugs
Barrel may be crimped at any rotational angle	Installation & inspection is simplified as there are no rotational indicators that the crimps must aligned with
Crimps may be made at any rotational angle to one another	Facilitates quick & easy installation even when the cables are routed against walls
Aluminum connector bodies	65% weight savings (on average) versus copper
Uses Industry-standard 22- & 33-ton crimp heads	Efficient installation while minimizing conversion costs
Efficient crimping process	Modified hex crimp design produces no burrs, eliminating the cost of secondary operations, minimizing plating damage & providing superior corrosion resistance
Crimping design	Produces installations where cables are nearly straight, facilitating harness design and installation
Patented integral oxide breaker	Improves conductivity while eliminating the need for messy anti-oxidant grease

For Aluminum-to-Aluminum Connections

• For splicing ACIT TLA-175 aluminum cables
• Lightweight tin-plated aluminum construction for applications up to 150 °C
