Polaris 3900 Sport Chain Guard (R0537800)
The chain guard is a replacement part made by Polaris. The same high-grade materials were used to manufacture the original factory part. Making this a genuine OEM product.
This chain guard was designed for the 3900 Sport model cleaners chain which is used instead of the belt-driven systems used on older model cleaners. This allows the cleaner to move faster and work harder covering the entirety of your pool's surface for the crystal-clear look.
This chain guard (black) is placed right next to the vacuum tube/feedpipe assembly and screws into the top of the frame, this secures the guard and allows for no movement while the chain rotates. Without this feature, the chain would be exposed to outside influence or damage which would end up disrupting the cleaner’s abilities during the cleaning process.
