Polaris 3900 Sport Chain (39-126)

This chain was designed to be a part of the drive train system which gives the cleaner the ability to move around the entirety of your pool's surface. Cleaning and sucking up dirt, debris, and other forms of mulch leaving behind a crystal-clear-looking pool.

This is located on the wheel sprocket assembly. This assembly is powered by the gearbox which rotates and moves the chain along, dispersing the rotating motion throughout the wheel assembly and other functioning parts. All of these work together to move the cleaner along your pool surface so it can perform its job.

Another great feature of having this chain is that it is made from metal as opposed to the old rubber belts that were produced for the older Polaris model cleaners. This prevents the chain from deteriorating or breaking down like a rubber belt would on a frequent basis. This gives the cleaner more power and the ability to operate faster than any other pressure-side In-ground pool cleaner.
