Product Description
The ILSCO D2057 is a high-performance, dual-barrel mechanical terminal designed to terminate two separate conductors to a single mounting point. Engineered for versatility and space efficiency, this lug is precision-machined from high-strength 6061-T6 extruded aluminum alloy. It is an essential component for electrical distribution panels, machinery wiring, and industrial control systems where multiple wire connections are required in a compact footprint.
Every D2057 is electro-tin plated to ensure exceptionally low contact resistance and to provide superior protection against oxidation and galvanic corrosion. Its AL9CU dual-rating provides the flexibility to safely terminate both copper and aluminum conductors in standard 600V systems or high-capacity 2000V applications.

Design & Performance
-
Twin Termination: Allows for the termination of two conductors into one lug, simplifying wiring and reducing the space needed on busbars or equipment pads.
-
Extruded Strength: The use of 6061-T6 aluminum ensures a rugged body that can withstand the high torque required for 2/0 AWG conductors without cracking or deformation.
-
Compact Footprint: Engineered to maximize surface area contact while maintaining a slim profile for tight electrical enclosures.
Key Features & Benefits
-
Versatile Range-Taking: A single lug part number covers a massive range of wire sizes, from small 14 AWG branch circuits to large 2/0 AWG feeders.
-
Mechanical Simplicity: No expensive hydraulic crimping tools or dies are required; installation is performed quickly with a standard 3/16" hex wrench.
-
Bimetallic Safety: Specifically designed to safely connect dissimilar metals (Aluminum to Copper) without the risk of thermal failure or corrosion.
-
Reusable Design: Unlike compression lugs, mechanical terminals are reusable, making them perfect for system upgrades, maintenance, or temporary power setups.
-
High Voltage Ready: Listed for use up to 2000V, providing a significant safety margin for commercial and industrial power distribution.
