Key features
- DIRECT BATTERY POWER CONNECTIONS - Replaces the standard bolt in a side-post battery terminal with a threaded stud, giving you a clean attachment point for accessory power and ground leads straight off the battery.
- SOLID BRASS CONSTRUCTION - Machined from solid brass for strong, corrosion-resistant electrical contact that holds torque when tightened against the battery terminal and stacked ring lugs.
- FITS SIDE-POST BATTERY TERMINALS - Overall length 1.750 inches, 5/8 inch hex nominal diameter, 3/8-16 coupler thread into the battery, 0.400 inch battery insert, with a 0.680 inch long 3/8-24 stud on the back end.
- ACCEPTS 3/8 INCH RING TERMINALS - Exposed stud accommodates one or several 3/8 inch ring terminals, making it easy to add multiple accessory circuits to a single battery post.
- IDEAL FOR ACCESSORY WIRING - Excellent for trailer brake controls, auxiliary power taps, and direct-to-battery circuits that help reduce noise in stereo, communication, and other electronic equipment.
