Product Description
The Marathon 97935 is a heavy-duty, single-barrel mechanical lug tap designed for secure high-capacity electrical connections. Engineered from high-strength aluminum alloy and finished with electro-tin plating, this connector provides superior conductivity and maximum corrosion resistance for both copper and aluminum conductors.
The specialized 2-hole mounting configuration offers enhanced anti-rotation stability, ensuring the lug remains fixed during high-torque installation and thermal cycling. This makes it an ideal solution for grounding, bonding, and power distribution in industrial switchgear and commercial panels.
