The Wirthco 30600 is a battery doctor top post battery terminal bolt.
Key features
- Direct-To-Battery Accessory Connections: Adds a 5/16-18 threaded stud above a top post battery terminal so one or several 3/8 inch ring terminals can tie into direct battery power for clean, reliable circuits.
- Solid Brass Construction: Machined from solid brass for strong, conductive contact at the battery post and dependable threads when tightening down ring terminals and accessory leads.
- Fits Top Post Batteries: Overall length 1.440 inches with a 1/2 inch hex body; coupler thread 5/16-18 female 0.70 inch deep accepts the factory cable connector bolt, and the 5/16-18 stud projects 0.400 inch for stacking terminals.
- Keeps Ring Terminals Clear Of Corrosion: Replaces the nut on the cable connector bolt and lifts accessory ring terminals up off the battery post, helping reduce noise in stereo, communication, and other electronic equipment.
- IDEAL FOR TRAILER BRAKES AND AUXILIARY LOADS - Well suited to trailer brake controls, auxiliary lighting, audio amplifiers, and RV or marine house circuits that need extra direct-power tie points at the battery.
Before you order
- Check the group size, terminal layout and cold-cranking amps against your current battery.
