Springfield Kingpin Offset Post 1610413-OSS, 13 Inch Stainless Steel, 1-3/4 Inch Diameter

The Springfield Kingpin Offset Post (1610413-OSS) is a stainless steel seat post designed for boaters who need to adjust seating position without changing their seat mount or base location. Part of the Springfield Kingpin Series, this post measures 13 inches in overall length with a 1-3/4 inch diameter, giving it the offset geometry that lets a helm or companion seat be repositioned relative to its base while keeping a secure, rigid connection.

Construction is heavy-duty stainless steel with a satin finish, built to hold up to marine environments including saltwater spray, sun exposure, and repeated seat adjustments. The post is designed to work with any Kingpin seat mount and standard base, both of which are sold separately, making it a straightforward upgrade or replacement component for boat owners already using the Kingpin seating system rather than a full seat mounting kit.

This is the standard (non-threaded) offset post in the Kingpin lineup. It ships retail packed in a clamshell with a 4-color label, ready for display or direct sale.
