This is the kind of replacement item that often solves a very specific maintenance problem without replacing a full assembly. The Bottom Lid Spring is a Hayward replacement part used in cleaners & parts applications, with part number RCX12101 for easier identification when matching existing equipment. Automatic cleaner parts are exposed to constant movement, debris, and pool chemistry, so worn pieces can quickly affect travel, pickup, or reliability. It is intended to restore the fit and function of the related Hayward assembly without replacing more equipment than necessary. Used during a focused repair, it can help bring the equipment back to a cleaner, more dependable operating condition. This makes it a smart replacement to keep available when servicing older Hayward systems that are otherwise still in good working order.
