Product Description
The Ilsco D970, commonly cross-referenced as the AU-250, is a high-performance double-barrel mechanical lug designed to consolidate two large conductors into a single terminal point. Ideal for transformer spades, bus bars, and industrial machinery, this lug provides a secure, high-torque connection for high-capacity electrical systems.
Precision-machined from high-strength 6061-T6 aluminum alloy and finished with electro-tin plating, the D970 is built to withstand heavy use while maintaining low contact resistance. Its AL9CU dual-rating makes it a versatile solution for terminating both copper and aluminum conductors in residential, commercial, and industrial projects.

✅ Key Features & Benefits
-
Space-Saving Design: The double-barrel configuration allows you to terminate two separate wires in a compact footprint, reducing the need for multiple single-wire lugs on a crowded bus bar.
-
Dual-Rated (AL9CU): Fully certified for use with both Copper (Cu) and Aluminum (Al) conductors, providing a single solution that prevents galvanic corrosion between dissimilar metals.
-
Corrosion Protection: The electro-tin finish provides a protective barrier against oxidation and harsh environments, ensuring a long service life.
-
Efficient Installation: Features chamfered wire entry for easy conductor insertion. The mechanical set-screw design allows for field installations with standard hex tools—no hydraulic crimping required.
-
High Structural Integrity: The 6061-T6 alloy body provides the strength necessary to withstand high tightening torques without deforming or stripping.
