The SPT5124 from Stinger is a PRO series 4-pack of 4 gauge barrier spade terminals in chrome finish, supplied as 2 red terminals for positive power connections and 2 black terminals for negative ground connections. The barrier design provides an insulated plastic collar at the crimp end, covering the wire-to-terminal transition to reduce the risk of short circuits from exposed metal. The number 10 fork hole suits the standard screw and stud sizes used in car audio amplifier and distribution installations.
Barrier spade terminals differ from standard spade terminals by incorporating a plastic insulated collar at the crimp end that covers the point where the wire enters the terminal body. This insulated barrier reduces the risk of exposed metal at the crimp joint causing short circuits or corrosion, providing a neater and safer termination in car audio power and ground cable runs.
The SPT5124 provides a matched set of 4 gauge barrier spade terminals covering both positive and negative connections. The chrome finish delivers a premium appearance consistent with the Stinger PRO series range, and the number 10 fork hole suits a range of screw and stud connection points used in car audio installations. A crimp tool suitable for 4 gauge terminals is required for correct installation.
4 gauge barrier spade terminal: Designed for crimp connection to 4 gauge power and ground wire, with a barrier design providing an insulated plastic collar at the crimp end for reduced short circuit risk.
Barrier design for insulated termination: The plastic insulated collar at the crimp end covers the wire-to-terminal transition, reducing the risk of short circuits from exposed metal and providing a cleaner, safer termination than standard uninsulated spade terminals.
Chrome finish: The chrome finish provides a premium appearance consistent with the Stinger PRO series range, suited to high-end visible installations in custom car audio builds.
4-pack with 2 red and 2 black terminals: Two red terminals for positive power and two black terminals for negative ground, providing two complete matched pairs for dual amplifier or dual accessory power and ground connection sets.
Number 10 fork hole: The number 10 fork hole suits the standard screw and stud sizes used in car audio amplifier terminals and distribution block connection points.

What is the difference between the SPT5124 and the SPT5104?
Both are PRO series 4 gauge chrome crimp terminals supplied as a 4-pack with 2 red and 2 black. The SPT5104 is a ring terminal with a 5/16 inch ring hole that fully encircles the stud. The SPT5124 is a barrier spade terminal with a number 10 fork hole that slides over the screw from the side. The barrier spade is suited to connection points where the fastener does not need to be fully removed for disconnection, and the insulated barrier provides additional protection at the crimp joint.
What does the barrier design provide over a standard spade terminal?
The barrier at the crimp end of the SPT5124 provides a plastic insulated collar covering the wire-to-terminal transition, reducing the risk of short circuits from exposed metal at the crimp joint. Standard spade terminals have an exposed crimp section without this insulation.
What is a number 10 fork hole?
The number 10 designation refers to the screw or stud size that the fork hole is designed to fit. A number 10 size suits the standard screw and stud dimensions used on car audio amplifier power terminals and many distribution block connection points. Contact us if you need to confirm compatibility with a specific connection point in your installation.
Do I need a crimp tool to install the SPT5124 terminals?
Yes. A crimp tool suitable for 4 gauge terminals is required for correct termination. Contact us if you need guidance on selecting the correct crimping tool for these terminals.
Are the SPT5124 terminals suitable for both positive and negative connections?
Yes. The pack includes both red terminals for positive power and black terminals for negative ground, covering both polarities. For professional installations, use red for positive and black for ground to maintain standard polarity identification throughout.
