Product Details

The Metra CUR438 is a professional-grade copper uninsulated ring terminal designed for 4 AWG wire with a 3/8-inch ring hole size. This package includes 25 terminals, making it ideal for car audio installations, marine electrical systems, RV battery connections, and high-current automotive applications.

Key Features:

  • Terminal barrel size: 4 AWG
  • Ring hole size: 3/8 inch
  • 100% copper construction for superior conductivity and corrosion resistance
  • Uninsulated design allows for heat shrink tubing or tape application
  • Can be crimped or soldered for secure connections
  • Compatible with solid or stranded wire

These copper ring terminals are essential for creating reliable, low-resistance electrical connections in high-current applications. The uninsulated design provides flexibility for custom protection methods and allows for visual inspection of the crimp or solder connection. Perfect for amplifier power and ground connections, battery terminals, starter motor connections, and other heavy-duty electrical applications where maximum conductivity is required.

Ordered my CTEK battery Charger on Wed night and received it on Fri morning. Super fast shipping. Will definitely buy from again.

I have dealt with them twice so far and they have been great both times. Price can't be beat and you can get someone on the phone nearly every time you call. Shipping is reasonable and fairly quick. I will definitely shop here again.

So far found what I've been looking for so I'm satisfied currently

Execellent retailer. Easy to buy from online. Got product quickly at a great price. I highly recommend!

Just placed order, waiting for shipment to arrive first

Had to do order twice. Hope I don't get charged twice.

Customer Care took care of my return and refunded the shipping after there was some order confusion. Thank you for taking care of everything!
