How can we help?

All three use the same UV-resistant pultruded fiberglass and include a belt, carabiner, and carry bag. The difference is height and flex:

• ST3 — 69" tall, 39" flex range, 3-piece construction. The tallest pole with the most flex, giving you the smoothest, most natural swim feel. Best for lap swimmers, triathletes, and performance training.
• ST2 — 47" tall, 25" flex range, 2-piece construction. A balanced mid-height option that works great for most people and pools. Best for families and fitness swimmers.
• ST1 — 24" tall, 7" flex range, 1-piece construction. Short and rigid by design. Best for water aerobics, therapy, resistance exercises, and swim spas.

Every kit ships with your selected pole (or poles for multi-piece models), one stretch cord, a swim belt, an anodized aluminum carabiner, and a carry bag. Adding an install base is optional — choose one if you need it, or skip it if you already have one mounted.

EPDM rubber (Shore-A 60 hardness). EPDM is highly resistant to UV, ozone, chlorine, and saltwater — it won't degrade from pool chemicals. Cords are available from 4.5ft to 20ft and stretch approximately 24% under normal swimming tension.

Pultruded fiberglass — the same material used in fishing rods and high-performance composite structures. It's lightweight, extremely durable, UV-resistant, and won't corrode from pool chemicals or saltwater. The multi-piece models (ST2 and ST3) use progressively narrower diameter sections joined by precision CNC'd anodized 6061 aluminum fittings to create the flex curve.

• Concrete Deck Base — Drill-in anchor for concrete, stone, or paver decks. Included with every kit at no extra charge.
• Threaded Wood Deck Base — Made of 316 stainless steel. Requires drilling into wood or composite decking and is secured with a heavy-duty nut (included).
• Arctic Spa Adapter — Threaded adapter that screws directly into the female threaded receiver built into Arctic Spas swim spas. No drilling or additional hardware required.

Already have a base installed from a previous Swim Tether? Select "I Already Have a Base" in the kit builder and we'll skip the base. Adding a base is always optional.

Absolutely. Beyond lap swimming, the Swim Tether is great for:

• Water aerobics — resistance training for upper and lower body (the ST1 is ideal)
• Aqua jogging — low-impact cardio without needing a deep pool
• Rehabilitation therapy — safe, controlled movement in water
• Strength training — resistance work with the belt or optional accessories

Yes. Cords, belts, carabiners, and bases can all be ordered individually. Contact us and we'll help you find what you need.

Yes. The concrete base needs a drill with a masonry bit — about 15 minutes. The wood deck base is also drill-in, secured with a heavy-duty nut that's included. The Arctic Spa Adapter simply threads into the built-in receiver on Arctic Spas swim spas — no drilling or extra hardware needed. Step-by-step instructions are included with every order.

As close to the pool edge as practical. The base should be on a solid, level surface (deck, coping, or spa rim). The pole will flex forward over the water — that's by design. Most installations are within 6–12 inches of the water's edge.

Absolutely. The pole lifts straight out of the base in seconds. The base stays permanently mounted, and the pole stores in the included carry bag. Most people leave the base installed and just pull the pole when they're done swimming.

Yes, but the pavers should be at least 12×12 inches and 2–3 inches thick for solid anchoring. Make sure they're set firmly and won't shift under load. If your pavers sit on sand or aren't fully stable, consider reinforcing with a concrete pad underneath.

Yes. You'll need a solid mounting surface near the pool edge — a concrete pad, wood deck, or composite platform all work. A 2" PVC pipe filled with concrete, a 4×4, or a 6×6 post can also serve as a mounting point. The base mounts to that surface, and the pole extends over the pool wall. See our above-ground installation guide for details.

Nope. In the kit builder, select "I Already Have a Base Installed" and you won't be charged for one. If you're unsure whether your base plate opening is the standard size (7/8" or larger) or the narrower size, send us a photo and we'll confirm which pole fitting you need.

The Swim Tether works in virtually any pool — in-ground, above-ground, swim spas, and plunge pools. We've even had customers install on a boat swim platform. The key requirement is a solid surface near the water to mount the base: concrete, wood, composite decking, or an Arctic Spa rim.

Our kit builder has a built-in calculator. Enter the distance from your base to the center of where you want to swim, and it recommends the right cord. If you're between sizes, go one size longer — you can always shorten the effective length by clipping the carabiner to a different loop on the belt.

Free returns within 30 days, no hassle. But our calculator is quite accurate, and going one size longer gives you flexibility. Cords can also be DIY adjusted to a shorter length by unscrewing the end clips, cutting to size, and re-assembling.

No — the Arctic Spa Adapter is designed specifically for swim spas manufactured by Arctic Spas, which have a built-in female threaded receiver. It won't fit other brands. If you have a different swim spa, the concrete or wood deck base will work if you have a solid surface nearby. Contact us if you're unsure — we'll help figure out the best mounting option.

The system is designed for normal swimming resistance, not pulling or hanging. There's no strict weight limit for swimming use — the cord and pole flex to absorb force progressively. The belt fits waists up to 48".

The ST1 is usually the best fit for swim spas — its short, rigid design works well in smaller spaces. If your swim spa is on the larger side (14ft+), the ST2 can also work. The kit builder's cord calculator will confirm the right cord length based on your measurements.

The fiberglass pole is UV-resistant and won't be damaged by sun or rain. That said, we recommend removing the pole and storing it in the carry bag when not in use — it protects against accidental damage, keeps it cleaner, and takes just seconds to pop in and out of the base.

Rinse everything with fresh water after each use — especially if you swim in saltwater or heavily chlorinated pools. That's it. The belt can be machine washed occasionally if needed. Avoid harsh solvents on the cord or pole.

With normal use and a freshwater rinse after each session, EPDM cords typically last 1–3 years depending on frequency of use and sun exposure. Signs it's time to replace: visible cracking, loss of elasticity, or the cord feeling stiff. Replacement cords are available separately.

Remove the pole and cord, rinse with fresh water, dry them off, and store in the carry bag indoors. The base can stay mounted year-round — it's stainless steel and designed to handle the elements. When spring comes, just pop the pole back in and you're ready to go.

Yes. EPDM rubber is specifically chosen for its resistance to chlorine, bromine, saltwater, ozone, and UV. A quick freshwater rinse after each swim is all you need to maximize cord life.
