Polaris 3900 Sport Double-Side Wheel (39-410)
The double-side wheel is a replacement part made by Polaris. This part is made from the same high-grade plastic material as the original factory part. Making this a genuine OEM product.
This part is designed to spin while allowing the wide trax tire to help the cleaner to move along the bottom surface of your pool. It also allows the cleaner to climb up and down the pool walls providing a deep clean for the entirety of your pool.
Just like the wheel screws, there are 3 of these parts and they are placed two on one side of the cleaner and locked into the frame and bottom housing. The third is placed on the opposite side. Also, there are two wheel bearings on each side of the wheel that gives it the ability to spin in either direction with ease.
