Our take on the T-Spec Crimp-on Ring Terminals

Make good connections

You'll get tight and secure connections for your amplifier's power and ground cables with a set of T-Spec's crimp-on ring terminals. You just insert the wire's stripped end and crimp the terminal in place for a long-lasting and worry-free electrical connection. This package includes five nickel-plated ring terminals with 3 red and 2 black covers. Warranty: 1 year. 

Good quality and dors what it is suppose to do
