Install Bay CUR410 Copper Uninsulated Ring Terminal 4 Gauge #10 - 25 Pack

The Install Bay CUR410 is a copper uninsulated ring terminal designed for clean, reliable crimped wire connections in automotive, marine, and powersports electrical installations. Built for 4 AWG wire with a #10 ring hole (0.190"), this terminal provides a solid, low-resistance connection point for grounding, battery, and high-current wiring applications.

The open, uninsulated barrel design allows for a direct crimp with standard terminal crimping tools, making it a go-to choice for professional installers who apply their own heat shrink or sleeve insulation after crimping. Pure copper construction ensures excellent conductivity and corrosion resistance compared to steel or aluminum alternatives.
