The SPT5211 from Stinger is a PRO series 4 gauge barrel wire coupler finished in Shoc-Krome chrome, designed to join two 4 gauge cables end to end in a single compact unit. Supplied as a single unit, it provides a high-power inline splice connection for 4 gauge power runs in car audio and automotive accessory installations.
A barrel wire coupler is used when two separate lengths of 4 gauge cable need to be joined inline without routing to a distribution block or terminal. The SPT5211 provides this connection in a compact chrome-finished unit, joining both cable ends securely within the barrel body. This is useful in installations where a single cable run is not long enough to reach the destination, or where a damaged section of cable needs to be replaced without re-running the entire length.
The Shoc-Krome chrome finish provides corrosion resistance and a premium appearance consistent with the Stinger PRO series terminal and adapter range. The SPT5211 is the 4 gauge counterpart to the SPT5210 1/0 gauge barrel coupler, covering the mid-level power cable gauge most commonly used in 4 gauge amplifier wiring kit installations. Connection method details should be confirmed with us before ordering to ensure the correct tooling is available for your installation. Supplied as a single unit per pack.
4 gauge barrel splice connection: Joins two 4 gauge cable ends inline in a single compact barrel unit, providing a high-power splice connection without routing to a distribution block or terminal.
Shoc-Krome chrome finish: The Shoc-Krome plating provides corrosion resistance and a premium chrome appearance consistent with the Stinger PRO series terminal and adapter range.
High-power connection: Designed for the current demands of 4 gauge power runs in car audio amplifier installations and automotive accessory applications.
Compact barrel design: The barrel form factor provides a clean, low-profile splice connection point that minimises bulk in the cable run compared to using two ring terminals and a junction block.

What is the SPT5211 used for?
The SPT5211 joins two 4 gauge cable ends inline in a single compact barrel unit. It is used when two lengths of 4 gauge cable need to be spliced together without routing to a distribution block or terminal, such as when extending a cable run or replacing a damaged cable section.
What is the difference between the SPT5211 and the SPT5210?
Both are PRO series Shoc-Krome barrel wire couplers with identical function and design. The SPT5210 is a 1/0 gauge coupler for the highest-powered installations, while the SPT5211 is a 4 gauge coupler suited to mid-level power installations using 4 gauge wiring kits. Select the gauge that matches the cable used in your specific installation.
What connection method does the SPT5211 use?
Connection method details are not confirmed in the available source data for this product. Contact us before ordering to confirm whether the SPT5211 uses set screw, crimp, or another connection method, and what tooling is required for correct installation.
Is the SPT5211 suitable for both positive and negative cable runs?
Yes. The SPT5211 is a barrel wire coupler and is electrically neutral, suitable for use on either the positive power or negative ground side of the installation.
Is the SPT5211 available in other cable gauges?
Contact us to confirm the full range of Stinger PRO series wire coupler options available in other cable gauges to suit your specific installation requirements.
