Metra Copper Uninsulated Ring Terminal

The Metra Copper Uninsulated Ring Terminal line gives you a dependable way to terminate power, ground, and battery cables in car audio, automotive, marine, and other 12-volt installations. Each ring terminal (also called a copper ring lug or non-insulated ring connector) is made of copper, so it conducts well and holds up to heavy current. It is sold under Metra's Install Bay installation hardware brand.

Key Features:

• Copper construction for good electrical conductivity
• Uninsulated design, so you can add your own heat shrink or insulation to suit the job
• Ring-style tongue that fits over a stud or bolt for a secure, vibration-resistant connection
• Barrel sized for a specific wire gauge, and a ring hole sized for a specific stud
• Suited to amplifier power and ground wiring, battery connections, and dual-battery setups

Crimp the terminal, and solder it if you want, to get a solid connection that lasts. The line covers a range of wire gauges and ring hole sizes, so you can match the terminal to your cable and mounting stud.
