What to Compare Before Buying
- Check that the seat base is designed for a 2-3/8-inch post, and confirm fit with the base manufacturer or product instructions.
- Compare the post’s 13-to-19-inch adjustment range with the height needed for your seating arrangement.
Compatibility, Size and Fit
The stated diameter alone does not identify every compatible seat base. Confirm the exact base and its retention requirements before selecting this post; do not assume that a matching measurement establishes compatibility.
Before You Decide
Confirm the base fit, required seating height, and applicable installation and use instructions for the post and boat seating system.
