Description
Professional 8 Gauge Ring Terminal Chrome, Set Screw, Deep Recess, Positive or Negative.
Product Overview
The Stinger SPT528 is a PRO-series 8 gauge ring terminal featuring a 5/16″ ring opening, oversized set screw connection, and a deep wire recess design for a clean, secure wire termination. Finished in chrome, this terminal delivers both a reliable electrical connection and a professional installation appearance exactly what you'd expect from Stinger's PRO terminal range.
One red and one black polarity rubber band are included, allowing the same terminal to be used for either positive or negative applications without purchasing separate terminal types. The oversized set screw provides a firm, tool-tightened mechanical hold on the 8 gauge wire, while the deep wire recess ensures the wire is fully seated and protected within the terminal body. A practical, quality choice for any car audio installer or DIYer looking to terminate 8 gauge power or ground cable with a clean, professional result.
