Why isn't the install base plate included?

We offer the install base plates as an add-on since most swim spa manufacturers have chosen to include them during production.

You can select a plate when building your kit below. Swim Tether installation base plates are available in Standard for concrete or Threaded for wood and composite.

Installation

Refer to our Installation Guide for step-by-step instructions on getting set up in less than 30 minutes!

Cord Length

The appropriate cord length for the ST3 Swim Tether is determined by various factors such as pool features and the swimmer's height and reach. Additional factors may include ledges, steps, the overall size of the swimming area or whether you choose to install further away from the pool edge.

  • 4.5 ft cord for most swim spas
  • 6 ft cord for use in swim spas and pools in the 12-14ft range
  • 8 ft cord for pools greater than 14ft

Comfort

For optimal comfort, place the belt on the front of your hip bones with roughly 2 inches of slack between the small of your back and the adjustable slider.

System Works Great!

This year we installed an 8' x 20' "container" pool - for those who don't know this is a SeaCan shipping container converted into a pool. Our pool has a max depth of 4' with a 10' length and a couple of shallower shelves at one end for the grandkids and sitting/lounging. We also have a 44" high railing that surrounds the container. I submitted a drawing of our setup to Swim Tether and Thomas was very helpful instructing where to mount our 6" x 6" post for the anchoring system. At his direction I installed the post 18" from the railing (at the edge of the pool) and at the height of the pool deck on our 4' deep section. The system works great and the pole while it does bend does not contact our railing which I wanted to avoid. We ordered the ST3 system as weren't sure which of the bungee lengths we would need. While the 4' cord works I found the 6' cord was perfect for front crawl, back crawl and back stroke. The 8' cord is too long for front crawl (I started contacting our shallower section) but does work for breast and back stroke. I was pleasantly surprised as to how quickly I adapted to the system and the strokes feel very natural. As you're not moving through the water there is more resistance as you swim however this is just a matter of scaling your workout accordingly. I'm really excited about this system as it will now allow us to get in meaningful swim workouts in our small pool. I'd highly recommend this system for anyone interested in swim fitness in a smaller pool!

We just bought a swim spa and realized a tether is a must have. This was easy to assemble and use. Highly recommended !
