Product Details
- 01 Mixed cable and stud connection layout
Six cable-entry points and six threaded studs provide flexible connection options for compatible main and auxiliary conductors. Assign each position in the approved cable schedule before installation. - 02 Direct tapered-post interface
The terminal mounts directly to a compatible automotive battery post. Positive and negative post diameters differ, so the correct orientation and post standard must be verified. - 03 Organized multi-circuit take-off
The consolidated terminal can reduce improvised lug stacking and create a clearer service layout. It remains a common electrical point; connected circuits are not isolated from one another.

Use a direct terminal or adapter when the connection starts at the battery. Use a remote post when the battery connection must be brought to an accessible panel or service point.
Applications
Auxiliary vehicle circuits
Organize multiple compatible accessory feeds or returns at the battery while maintaining a defined cable map.
Car audio and aftermarket installations
Connect main audio power and supporting accessory conductors through a structured terminal arrangement, with appropriate circuit protection.
RV, marine and special-purpose equipment
Consolidate several battery-connected cables where direct access, inspection and serviceability are required.
Application examples describe potential use cases, not verified fitment to a particular vehicle. Confirm polarity, cable size, protection, mounting space, environmental exposure and the approved service procedure before installation.
