Fit Guide

Which Fitting Do You Need?

Look at your base and match it below. Narrow and Standard poles are not interchangeable — picking the right one means it fits the first time.

How to Tell Which You Have

Most Swim Tether poles take a Standard fitting. You need a Narrow fitting only if you have a factory-installed swim-spa base — a flush metal anchor cup set into the deck, usually held by screws.

Find your base in the photos below. Still unsure after looking? Measure the opening, or send us a photo and we'll confirm.
