Product Description
The Ilsco D899 is a high-capacity, dual-rated aluminum mechanical terminal lug designed for heavy-duty power distribution. Featuring a two-port design, it allows for the secure termination of two large conductors within a single, compact block, making it ideal for panelboards, switchgear, and motor control centers where space is at a premium.
Precision-machined from high-strength 6061-T6 aluminum alloy, the D899 is electro-tin plated to ensure a low-resistance connection and superior protection against oxidation. Whether you are using copper or aluminum wiring, this AL9CU-rated connector provides a reliable, gas-tight mechanical bond.
