CT-SL42-600 Stacked Mechanical Lug — 4-Conductor, 2-Hole, Dual-Rated AL/CU, 2 AWG–600 kcmil

The Conversions Tech CT-SL42-600 is a dual-rated stacked mechanical lug that terminates up to four aluminum or copper conductors at a single two-hole pad. The stacked two-tier port arrangement minimizes connector width, freeing gutter space in panelboards, switchboards, transformer cabinets, and service-entrance equipment. The body is machined from high-strength extruded aluminum alloy and electro tin-plated for low contact resistance and corrosion protection with both aluminum and copper conductors.
