Hayward AC035 Roller Assembly (CAX-3509) prostar and application-correct once completeA roller assembly helps support the moving action inside a compatible chemical feeder, and this Hayward AC035 version uses the CAX 3509 reference. Internal feeder components like this are important because they directly influence how smoothly the unit can drive and manage its dosing mechanism. This part has practical value because replacing a worn roller assembly can help restore cleaner feeder action without requiring replacement of the entire unit.
