  • heavy duty but diameter was to big around for my seat.
Size: 12" - Bulk Packaging
Great fast shipping, great quality product, just wrong size for my 2017 tracker boat seat.

  • Good condition
Size: 12" - Bulk Packaging
The info said it was used but it looks like new. Fits my Atwood seat and cost half what a new post cost. Good deal.

  • You do not get the part number they are advertising.
These seat posts are advertised with the correct part number 238615-1 for a 15 inch extension, which, according to the Attwood manufacturer's catalog, are supposed to be 15" above the floor, roughly 17" overall. They ship you 12" extension posts. (14.5" overall length). We immediately sent them back, and found an other vendor, who hopefully is providing the product they are advertising. A complete waste of time and money. ... show more

  • Not an extension
Size: 11" - Bulk Packaging
Not an extension for 238 series posts. Wanted to extend my boat seat and while this does have a slot for it its not flared out so doesnt allow you to slide in another pole to "extend" it so its not an extension just a post
