Description
Stinger SPT5211 PRO Series 4 Gauge Shoc-Krome Barrel Wire Coupler for High-Power Cable Splicing
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.
Product overview
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.
