Product Description
The ILSCO D2799 is an industrial-grade, single-barrel mechanical terminal lug engineered for high-capacity power distribution. Precision-machined from high-strength 6061-T6 aluminum alloy, this lug is designed to terminate massive conductors ranging from 4 AWG up to 600 kcmil (MCM). It is a critical component for terminating large feeders in switchgear, transformer secondary connections, and industrial control panels.
Every D2799 is electro-tin plated to ensure exceptionally low contact resistance and to provide a permanent barrier against atmospheric and galvanic corrosion. As a dual-rated (AL9CU) connector, it is certified for the safe termination of both copper and aluminum conductors at operating temperatures up to 90°C.
