Blue Sea PowerPost Dual 1 x 5/16" and 1 x 3/8" Studs With Insulators

The Blue Sea PowerPost Dual 1 x 5/16" and 1 x 3/8" Studs With Insulators is essential for reliable marine electrical distribution on modern boats. Designed for anglers, cruisers, and serious boaters, this dual-stud system provides separate connection points for high-amperage circuits, making it ideal for running multiple systems simultaneously.

Engineered with dual stud sizes—a 5/16" and 3/8"—this assembly accommodates both primary and secondary distribution needs without oversizing cable terminals. The integrated insulators help to reduce the risk of accidental shorts and corrosion at connection points, which is particularly important in the salt-spray environment of coastal fishing and extended cruising.

This stud assembly is perfect for boats transitioning to dual-bank systems or upgrading aging electrical infrastructure. It is compatible with 12V or 24V battery configurations, making it a versatile choice for various marine applications.
