Good product.
Size: 13-Inch
Very good product but it did not worked for my boat. The bushing did not fit all the way in the base hole do to the plastic ball at the bottom of the bushing being bigger that the hole in the base. Not for 17 FT Deep V older model Lowe bass boat.

Keeps you upright on the pontoon

This Atwood post has been a great replacement while being able to still use the factory bases. They are not adjustable however are a reasonable replacement that work great and install effortlessly.
