Product Description
The Blackburn ADR35-22 is a high-performance, two-conductor mechanical lug designed for reliable power distribution and grounding applications. Engineered for versatility, this lug allows for the secure termination of two independent aluminum or stranded copper conductors to a single mounting surface, such as a busbar or panelboard interior.
Precision-extruded from high-strength 6061-T6 aluminum alloy and electro-tin plated, the ADR35-22 ensures maximum conductivity while preventing the oxidation and galvanic corrosion typical in dual-metal connections. Its two-hole mounting tongue provides superior anti-rotation stability, making it the preferred choice for mission-critical industrial and commercial electrical systems.

Key Features & Benefits
-
Dual-Rated Versatility: Fully certified for use with both Copper (Cu) and Aluminum (Al) conductors, providing a single solution for various job site requirements.
-
Stable 2-Hole Mount: The dual-bolt tongue with 1.75" NEMA spacing ensures a massive contact area and prevents the lug from twisting during high-torque cable installation.
-
Corrosion Protection: Tin plating provides low contact resistance and protects the aluminum body from harsh environmental conditions and chemical reactions.
-
No Specialized Tools: Features high-pressure Allen-head set screws that create a gas-tight bond using standard hex keys—no expensive hydraulic crimpers or dies needed.
-
Space-Efficient: Consolidates two large conductors (up to 350 MCM) into one footprint, saving valuable space inside gutters, switchgear, and enclosures.
