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
Whether you need a Narrow or Standard fitting comes down to your base — the anchor point your pole drops into, mounted on the edge of a pool or built into the shell lip or topside of a swim spa. The two fittings aren't interchangeable, so it's worth a quick check before you order.
Most bases — including ours and many factory ones — take a Standard fitting; a handful of factory swim-spa bases take a Narrow one. You can't tell from where it's mounted, so find your base in the photos below. Still unsure? Measure the opening, or send us a photo and we'll confirm.
